Dynamically Assigning Values To Textbox From Array
Oct 20, 2011
in Javascript I need to dynamically assign the values of textboxes from an array. For example, The textbox ids are box0,box1,box2 and the array is [0,1,2]. Here i need to assign 0 to box0 and 1 to box1 and 2 to box2.
I am trying to assign values to a bunch of form fields. However, I don't want to loop through EVERY field in the form, just a specific subset of fields. The fields I am trying to change are all named similarly myField1, myField2, myField3.So, my thought is that I would like to use a for loop and loop through the appropriate fields by simply incrementing a variable and appending it to the end of the string "myField" in order to change the appropriate field.How can I evaluate "myField + iterator" into a useable reference to change the value of said field?
So I am working on an excercise that the User puts in a Lastname, Firstname, and a score via textboxes. When the user pushes the add student score it should show up in the text area with this format " Brown, John: 92". When looking at the logic, I understand that each text box will need to be different arrays if im right, and then I will have to concat all three arrays into the format and assign it to a variable. Then assign the variable to the value of the text area. I just cannot seem to put the function together or how you would go about it. how to go about putting it together. The first code is my body of HTML I'm working with.
I am taking a js class and there is one minor bug that is driving me crazy with this assignment.
First, here is the code I wrote, then my question:
var games = ["Jacks","Chutes and Ladders","Extreme Uno","Bopit","Barbie Doll"]; var price = [4.00,15.99,25.00,27.99,32.00]; var inventory = [40,15,30,20,40];
[Code.....
I can't (just before this line) assign 0 to each array item - to get it defined because if the user goes back in and adds more, it will always reset the number back to 0, which is not what I wanted.
I tried adding an if..else statement instead, but cannot figure out how to get that to work?
I want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"]; function create(){ var array=[];
I have a function whose parameter is a reference the element that called it:
function someFunction(el) { ... }
The function is assigned to the onclick event of some elements in the HTML source:
<input ... onclick="someFunction(this);" ...>
and dynamically to others:
elRef.onclick = someFunction;
When someFunction() is called from the statically-assigned onclick, el is a reference to the element. But when it has been added dynamically, el will be either undefined (IE) or 'event' (Mozilla et al).
To assign the right value to el, I can test if el exists and if it does, whether its constructor is some type of HTML element or 'Event'. But IE doesn't support the constructor property for elements (or have I just not found it yet?) nor does it understand 'Event' the way Mozilla does. Code:
I am currently putting together a trivia game and I have stored several items in an array for example the questions, and the answers, points value... etc.
but my dilemma is I have to assign an "id" to the elements in the the array so i can use the function getElementById() to call the information. I do not have a clue how to do this.
*** also the second issue is my array is showing an error as UNDEFINED BUT i have declared it in "var triviaArray"
this is my array:
var triviaArray = new Array [ triviaArray["What's the capitol of Canada?","TORONTO","VANCOUVER","OTTAWA","QUEBEC",10,"choice3"], triviaArray["How old was Michael Jackson when he died?","35 yrs","50 yrs","40
I'm putting together an events calendar athttp:[URL].. Each event is a li item, and I use jQuery to assign the class "no-left-m" (no left margin) to li:nth-child(3n+1) for CSS layout purposes. I've also added the ability to show only events in certain categories. Unfortunately, the initial jQuery assigns the classes to li items from the DOM, and doesn't take into account the show/hide. This means that when I show only a single category, the margins are off.
[Code]...
how I can assign my classes dynamically to nth-child(3n+1) of *visible* items only?
I am trying to assign a value to a java variable inside the script that I am calling via ajax but once the call is over it shows variable as undefined:
When I leave the first textbox (taborder 1), I need to check and see if the textbox contains avalue. If it does, then I need to check and see if the second textbox (taborder 2)contains a value. If it doesNOT, then I need to loadthe second textboxwith "100" and highlight (select) the text. I am adding a blur event to all the column one textboxes as they all contain"rawCount" in the id. Here is my blur event code:
$(document).ready(function(){ $('input[id*=rawCount]').bind('blur', function (event) { // Code to go here }); });
What I am trying to do isadd thecode tocheck and update thecolumn two textbox in the corresponding row (same index)to the blur event of the column one textboxes without having to loop the array each time to find the current textbox array position. Since it is adding the blur event, it has to be possible.
I'm trying to assign the values from the JSON data returned when I run this code into an array that's outside the callback function. The data is multidimensional, and I have been able to use this data within the callback function. However I want to use it outside that function. i.e. the jsdata returned in the code below is to be used outside the function
Code: $.getJSON('../fxns/status.php',function(jsdata){ //do some stuff with JSON data or pass to global variable[code]..........
How to process textbox values/ call textbox values in JS through a Java program.My text box values are dates. I have to process these dates. Like in online banking we select day to know our transactions. After submitting we get results. remember my files are in my directory only. No need of database. My files are look like 20100929, 20100930, 20101001
For epoch_classes.js, epoch_styles.css u can download coding from this link : http:[url].....
In my coding, ys, ms, ds represents year starting, month starting, starting day...ye, me, de represents end...start,end gives file names in the format of yyyymmdd.now i want to process files from 20100101 to 20100930
means from date is 2010/01/01 and to date is 2010/09/30
if i press submit button the files from 20100101 to 20100930 are processes
here ys=2010 ms=01 ds =01 and ye=2010 me=09 de= 30
For this how do i call these textbox values (from date text box and todate) to another program (java)
I am doing an application with two dropdown boxes.Once we change the value of first drop down using database values ,the values in the second drop down should change..then click on done it should display the data from databse.. first dropdown :contains country names second dropdown :contains city of particular country..My problem here at is displaying values on second drop down based on first drop down selection:
function read() { var numbers = new Array(); for (i = 0; i < field.length; i++) numbers[i] = document.test.checkboxName.value; var counter=0;
[Code]...
I want to read the values of the checkboxs and store the vlaues into an array (there are more than 1 checkboxs) the form name is text and the names of the check box = checkboxname
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code: var flag; for (i=0;i<=pdfs.length-1;i++) { flag = 1; for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.

and what this function does it count the number of Characters that have been typed in a Textbox. so i am displaying the remaining characters. So that is working fine on my example because the Element is known at Early Binding. Now my question is what if the textbox is created dynamically ?
contentbox
this is the name of the Textbox in my example.
how do we use a J Query in Dynamically created Textbox.
I have to define a textbox in html whose maximum size should be 3.Now If I am entring -100 then these are 4 characters but I want that user should allow to enter 100 or -100.If I define size="3" then it will not allow -100. so i want to know can we define size of the textbox dynamically,i.e. if I enter
- sign then size will increase to 4 else it should be 3.can we do this using js?
I'm not very familiar with Javascript, only PHP and ASP. I want to be able to have a user click an image and have text be inserted into the textbox where the cursor is at.
