As3 load text file array

Indicates whether an object has a specified property defined. Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter. Removes the last element from an array and returns the value of that element. Indicates whether the specified property exists and is enumerable. Adds one or more elements to the end of an array and returns the new length of the array.

Sets the availability of a dynamic property for loop operations. Public Constants. Property Detail. Implementation public function get length : uint public function set length value: uint : void Example How to use this example The following code creates an Array object names with the string element Bill.

It then uses the push method to add another string element Kyle. The length of the array, as determined by the length property, was one element before the use of push and is two elements after push is called. Another string, Jeff , is added to make the length of names three elements. The shift method is then called twice to remove Bill and Kyle , making the final array of length one. Throws RangeError — The argument is a number that is not an integer greater than or equal to 0.

More examples Creating an Array instance. The following example creates a new Array object with an initial length of 3, populates the array with the string elements one , two , and three , and then converts the elements to a string.

The following example creates the Array object myArr with no arguments and an initial length of 0: Copy. The following example creates an Array object with 5 initial elements, with a length of 5, and populates the first element with the string "one" , and adds the string element "six" to the end of the array by using the push method: Copy. AS3 function concat Returns Array — An array that contains the elements from this array followed by elements from the parameters. More examples Querying an array.

The following code creates four Array objects: The numbers array, which contains the numbers 1 , 2 , and 3. The letters array, which contains the letters a , b , and c. The numbersAndLetters array, which calls the concat method to produce the array [1,2,3,a,b,c].

The lettersAndNumbers array, which calls the concat method to produce the array [a,b,c,1,2,3]. Returns Boolean — A Boolean value of true if all items in the array return true for the specified function; otherwise, false. The following example tests two arrays to determine whether every item in each array is a number.

It also outputs the results of the test, showing that isNumeric is true for the first array and false for the second: Copy. Returns Array — A new array that contains all items from the original array that returned true. The following example creates an array of all employees who are managers: Copy. Example How to use this example The following example runs the trace statement in the traceEmployee function on each item in the array: Copy.

The following example also runs the trace statement in a slightly altered traceEmployee function on each item in the array: Copy. Returns int — A zero-based index position of the item in the array. If the searchElement argument is not found, the return value is The following example displays the position of the specified array: Copy. Returns String — A string consisting of the elements of an array converted to strings and separated by the specified parameter.

The following code creates an Array object myArr with elements one , two , and three and then a string containing one and two and three using the join method. The following code creates an Array object specialChars with elements , , - , and a blank space and then creates a string containing Then, using a for loop, it removes each type of special character listed in specialChars to produce a string myStr that contains only the digits of the phone number remaining: Returns Array — A new array that contains the results of the function on each item in the original array.

The following example changes all items in the array to use uppercase letters: Copy. More examples Retrieving values and removing array elements. The following code creates an Array object letters with elements a , b , and c. The last element c is then removed from the array using the pop method and assigned to the String object letter. AS3 function push Returns uint — An integer representing the length of the new array. More examples Inserting array elements. The following code creates an empty Array object letters and then populates the array with the elements a , b , and c using the push method.

The following code creates an Array object letters , which is initially populated with the element a. The push method is then used once to add the elements b and c to the end of the array, which is three elements after the push. Returns Array — The new array. More examples Sorting an array. The order of the array elements is then reversed using the reverse method to produce the array [c,b,a].

The following code creates the Array object letters with elements a , b , and c. The shift method is then used to remove the first element a from letters and assign it to the string firstLetter. Returns Array — An array that consists of a range of elements from the original array. The following code creates an Array object letters with elements [a,b,c,d,e,f].

The array someLetters is then created by calling the slice method on elements one b through three d , resulting in an array with elements b and c. The array someLetters is then created by calling the slice method on element two c , resulting in an array with elements [c,d,e,f]. The array someLetters is then created by calling the slice method on the second to last element from the end e , resulting in an array with elements e and f.

Returns Boolean — A Boolean value of true if any items in the array return true for the specified function; otherwise false. Related API Elements every. The following example displays which values are undefined: Copy. AS3 function sort Sorting is ascending a precedes b.

The array is modified to reflect the sort order; multiple elements that have identical sort fields are placed consecutively in the sorted array in no particular order. All elements, regardless of data type, are sorted as if they were strings, so precedes 99, because "1" is a lower string value than "9". If you create a custom function, you call the sort method, and use the name of your custom function as the first argument compareFunction Parameters The URLStream class also lets you close a stream before it finishes downloading.

The downloaded data is available as raw binary data. When reading data from a URLStream object, use the bytesAvailable property to determine whether sufficient data is available before reading it. An EOFError exception is thrown if you attempt to read more data than is available. The httpResponseStatus event is delivered before any response data. When you build dynamic applications, it can be useful to load data from external files or from server-side scripts.

This lets you build dynamic applications without having to edit or recompile your application. Then your application can load the contents of a static text file instead of querying the database each time.

The external document, params. The file contains two parameters, monthNames and dayNames. Each parameter contains a comma-separated list that is parsed as strings. You can split this list into an array using the String.

If the remote document contains name-value pairs, you can parse the data using the URLVariables class by passing in the contents of the loaded file, as follows:. Each name-value pair from the external file is created as a property in the URLVariables object. Each property within the variables object in the previous code sample is treated as a string.

If the value of the name-value pair is a list of items, you can convert the string into an array by calling the String. The three possible values for the URLLoader. The following code demonstrates how setting the URLLoader. When the file has completely downloaded, the Event. A server-side script can process the user name and password, validate it against a database, and return confirmation of whether the user-supplied credentials are valid.

The following snippet creates a URLVariables object named variables, which creates a new variable called name.
