Returns -1 if value is not found. Overridden to return a nicely formatted string representation of the array with its elements. Returns the array in reverse sequence. If no argument is given or if the argument is true the array itself will be changed.
Otherwise it will remain unchanged. Returns the first element and removes it from the array, reducing the array's length by 1. Returns the array excluding the elements that are included in the list of arguments. Returns all the elements that are associated with the given CSS class name. If no parentElement id given, the entire document body will be searched.
List of cached observers. Part of the internal implementation details of the object. Returns true if the left mouse button was clicked. Use this function to abort the default behavior of an event and to suspend its propagation. Traverses the DOM tree upwards, searching for the first element with the given tag name, starting from the element that originated the event. Private method, do not worry about it. Clears all cached observers from memory.
Creates one instance of this object that will call the function repeatedly. This method is what will be called by the timer. It, in turn, will invoke the callback method passing the object itself. The function to be called. A handle to the underlying timer object responsible for repeatedly invoking the callback method.
Calls the given iterator function passing each element in the list in the first argument and the index of the element in the second argument. This function is a way to test the entire collection of values using a given function. It will return false otherwise.
If no iterator is given, then the test will be if the element itself resolves to true. You can simply read it as "check if all elements pass the test. You can simply read it as "check if any element passes the test. Calls the iterator function for each element in the collection and returns each result in an Array , one result element for each element in the collection, in the same sequence. Calls the iterator function for each element in the collection and returns the first element that caused the iterator function to return true or, more precisely, not-false.
If no element returns true, then detect returns null. Calls the iterator function for each element in the collection and returns an Array with all the elements that caused the iterator function to return a value that resolves to true. This function is the opposite of reject. Tests the string value of each element in the collection against the pattern regular expression. The function will return an Array containing all the elements that matched the regular expression.
If the iterator function is given, then the Array will contain the result of calling the iterator with each element that was a match. Tries to find the given object in the collection. Returns true if the object is found, false otherwise. Returns the collection broken in groups containing as many items as specified by the first argument. If the quantity of items in the initial collection is not divisible by the number in the first argument, the resulting empty items at the end of the last group will be filled with null or with the value of the second argument, if provided.
Quick example: ['a','b','c','d']. Combines all the elements of the collection using the iterator function. The iterator is called passing the result of the previous iteration in the accumulator argument. The first iteration gets initialValue in the accumulator argument. The last result is the final return value.
Calls the method specified by methodName in each element of the collection, passing any given arguments arg1 to argN , and returns the results in an Array object. Returns the element with the greatest value in the collection or the greatest result of calling the iterator for each element in the collection, if an iterator is given.
Returns the element with the lowest value in the collection or the lowest result of calling the iterator for each element in the collection, if an iterator is given.
Returns an Array containing two other arrays. The first array will contain all the elements that caused the iterator function to return true and the second array will contain the remaining elements.
If the iterator is not given, then the first array will contain the elements that resolve to true and the other array will contain the remaining elements. This can also contain the index of the element. Retrieves the value to the property specified by propertyName in each element of the collection and returns the results in an Array object. Calls the iterator function for each element in the collection and returns an Array with all the elements that caused the iterator function to return a value that resolves to false.
This function is the opposite of findAll. Returns an Array with all the elements sorted according to the result the iterator function call. Returns an Array with all the elements of the collection. Merges each given collection with the current collection. The merge operation returns a new array with the same number of elements as the current collection and each element is an array let's call them sub-arrays of the elements with the same index from each of the merged collections.
If the transform function is given, then each sub-array will be transformed by this function before being returned. Quick example: [1,2,3]. Returns an Array with the keys of all items. Returns an Array with the values of all items. Combines the hash with the other hash passed in and returns the new resulting hash. Returns all the items of the hash in a string formatted like a query string, e. Overridden to return a nicely formatted string representation of the hash with its key:value pairs.
Creates one range object, spanning from start to end. It is important to note that start and end have to be objects of the same type and they must have a succ method. Checks if the given value is part of the range. Returns true or false. When the corresponding event occurs all the registered objects that contain a method with the appropriate name will have that method called.
The object passed in the responderToRemove argument will be removed from the list of registered objects. Runs through the list of registered objects looking for the ones that have the method determined in the callback argument. Then each of these methods is called passing the other 3 arguments. If the event is onException , the transport argument will have the exception instead and json will not be passed. Sets the desired options for the AJAX operation. Returns true if the AJAX operation succeeded, false otherwise.
Creates one instance of this object that will call the given url using the given options. The onCreate event will be raised during the constructor call. Important: It is worth noting that the chosen url is subject to the browser's security settings.
In many cases the browser will not fetch the url if it is not from the same host domain as the current page. You should ideally use only local urls to avoid having to configure or restrict the user's browser. Thanks Clay. This method is typically not called externally. Call this only after the AJAX call is completed. It is called by the object itself when the AJAX call status changes. It is already called during the constructor call. List of HTTP headers to be passed with the request.
This list must have an even number of items, any odd item is the name of a custom header, and the following even item is the string value of that header.
Example: ['my-header1', 'this is the value', 'my-other-header', 'another value']. The character encoding used in the body of a request especially POST requests. UTF-8 should be enough in most cases, but if you know what you're doing, you can use a different encoding. Events , and the HTTP status codes. Custom function to be called when the AJAX call completes successfully. Custom function to be called when the AJAX call completes with error.
Custom function to be called when an exceptional condition happens on the client side of the AJAX call, like an invalid response or invalid arguments. The function used will receive two arguments, containing the Ajax. Request object that wraps the AJAX operation and the exception object. A class that will determine how the new content will be inserted. Applies only to Ajax. Updater objects and if nothing is specified, the new content will completely replace the existing content.
If an Insertion -derived class is given, the content will be added to the existing content. It can be Insertion. Before , Insertion. Top , Insertion. Bottom , or Insertion. Determines if script blocks will be evaluated when the response arrives.
Updater objects. Determines the progressive slowdown in a Ajax. PeriodicalUpdater object refresh rate when the received response is the same as the last one. For example, if you use 2, after one of the refreshes produces the same result as the previous one, the object will wait twice as much time for the next refresh.
If it repeats again, the object will wait four times as much, and so on. Leave it undefined or use 1 to avoid the slowdown. Interval not frequency between refreshes, in seconds.
PeriodicalUpdater objects. This object contains two properties: containers. It is called by the object itself when the response is received. It will update the appropriate element with the HTML or call the function passed in the insertion option.
The function will be called with two arguments, the element to be updated and the response text. This value will be passed straight to the Ajax. Updater 's constructor. Defaults to 2 seconds. This number will be multiplied by the current decay when invoking the Ajax. Updater object. The handle to the timer being used to notify the object when it is time for the next refresh.
It is called by the object itself to start performing its periodical tasks. Causes the object to stop performing its periodical tasks. After stopping, the object will call the callback given in the onComplete option if any. It is called by the currently used Ajax. Updater after it completes the request.

Updater and then check it's. You can probably assume since it's an onComplete event then the referenced element is going to be changed. I don't think you can go without an onComplete handler, unless you want to rewrite the prototype ajax API.
However you do not have to directly pass a closure to the onComplete handler. Btw, I'm not excluding the possibility that there may be a method in the prototype API that will do something similar. I'm not that familiar with prototype. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Learn more.
