Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code.This does not seem to be working for me though. Here is what I have thus far (in short):
<script language="javascript">
var teamNames = new Array(3);
teamNames[0]="South Africa";
teamNames[1]="Mexico";
teamNames[2]="Uruguay";
[Code]...
I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far.
how to do you add elements to an array? am looking at section dealing with arrays in JS Bible, can't find how you add to an array.. in the last few years I've been doing much more Java than JS, am used to Java, where you can't add elements to an array, but use a Vector instead.. and it's very easy to add to it (use add() method..) how to you add elements to an array in JavaScript..
I looked up array obj, don't see method to add to array.
I'm trying to solve a problem with JS textbox array without success. I have two buttons in my page: PLUS and MINUS; at every click on PLUS a new textbox named 'dear' is generated. So, if one clicks, say, 3 times the output is something like:
dear[0] dear[1] dear[2]
The length property is accessible; alert(dear.length) gives Ɖ', correctly. The prolbem is that is not possible to delete a textbox, clicking on MINUS button. The thing I'd really need to do is to delete from the array (and in consequence from video) the last textbox created, when one clicks on MINUS button.
Pop() and Splice() methods do not work, unfortunely... This is the exact code of my page:
Here's what I'm trying to do: 1) I get reference to a div that's on my page: var theDiv = $("#" + divID); 2) Now I want to add a custom attribute tag to it, so for instance I want to add "winWidth" so that the div object now contains "winWidth=" for instance. 3) I want to set winWidth now since it's part of theDiv to a value
I'm not sure how to really do 1 + 2. I need to do this on the fly because some javascript logic later will add these attributes dynamically to the div... outside of what the original div had...I don't care what it had, I know I have it now in a JS variable and now I want to both add some new attributes to the div, and then set them on the fly. I don't need these attributes to be on my page, I just need them added to my div variable reference.
For some reason my script only works when I have at lease two checkboxes. To simulate the problem just run it once with two html input checkbox elements
-> check one checkbox and press submit -> it works -> Now remove one input checkbox field and check the remaining checkbox & submit -> Bamm doesn't work...
I've written several utility pages that use a dynamically created iframe. The iframe typically has a form that is populated by the main page. Then the form is submitted to be processed, and the returning page does something -- call a function on the main page, change a variable on the main page, etc.
All this stuff I created works on IE. Sorry, didn't have other browsers available to test. Now I have access to a machine with FF, and none of these scripts work.
So, short and sweet: What is the proper way to reference a form on an iframe from the parent doc in firefox? Also, call a function from the parent to the iframe, and vice-versa, call a function on the parent doc from the iframe when it loads?
This references the #Tags element which is an input text box. I would like this function to run on another element also (#Tags2). So if either the #Tags or #Tags2 text boxes are used, the function runs.How can I extend this function rather than duplicating it?
I am loading a set of icons using an array. The reason for this is that the icon set will be different depending on what some PHP code has given to the JavaScript.
My code currently looks like this.
Code:
var things_to_load = new Array(); things_to_load['header_cursors'] = new Array( 'default' , 'pointer' ); things_to_load['header_icons'] = new Array( '../img/triggers/to-roll/undo.png' , '../img/triggers/add.png' ); things_to_load['header_labels'] = new Array( 'undo' , 'add' );
[Code].....
The problem I have is that the click function gives the error "things_to_load.header_clicks[c] is not a function".
This makes sense as presumably the click function is saving the value and not what that value references.
how I can get this code to save the function not the string referencing it?
[code]So data2 has a length, but data2.body is undefined, data2.find() tells me find is not a function, data2 prints out the html, and yet I can't find anything which gives me just the body.
I am experience some problems reading a form variable from a Javascript function. The point with this particular variable is that its name has the following syntax:
<input name="tx_impexp[tt_content:159]"/>
I want to set this var to 1 from my javascript function, so I tried to execute the following line of code:
Error: missing ] in index expression document.frm_1.tx_impexp[exclude][tt_content:159].value=1 --------------------------------------------------------------|
It seems Javascript expects to close down the bracket at the position marked...An easy solution would be to change my var syntax but the point is that I cannot since I am using an already made script and I should not modify it.
Just wandering if this is due to a syntax error defined according to Javascript specification language or there is something wrong with this.
I having been trying to make the data from generated (using div tags) pairs of textboxes into two separate arrays, a[] and b[]. I thought that if I label each text box pair a[i] and b[i] that would be enough to include the respective element in each array but that hasn't seemed to work. In fact. the only way I managed to retrieve the values from the text boxes was using "getElementById" and resorted to a for loop in order to make the arrays but that method appears to be able to get elements from only one pair of text boxes. Code:
how to add extra properties to html elements as I was storing data in html attributes. After looking at some others code including Raphael and this addEvent code. [URL] They seem to treat objects just like an array. obj[property] = value; This would have been extremely helpful to know previously as I have needed to be able to include variables in property names - but have resorted to making the whole thing a string and calling exec() on it.
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.
I'd like to reorganize the third, fourth, fifth and sixth, as well as any elements thereafter in an array in random order:
var a = new Array('first','second','third','fourth','fifth','s ixth','etc')
In other words, the first, second and third element should remain in position 0, 1 and 2, while the fourth, fifth and sixth, etc. should appear in random order.
I have HTML tags stored in XML. I want to be able to use these HTML elements with Javascript, just as you can with elements in document.body. How can it be done? (And don't try and tell me I should use server-side because I have written it all for Javascript and the project is nearly complete minus this and there are practical reasons for not doing this server-side. After all, anything is possible with Javascript!)
Let me explain:
- I have HTML templates such as this [URL]
- I want javascript to populate these templates then add them to my page
- The only way I know javascript can get this kind of data is by parsing XML
- I want to parse the XML then be able to use the HTML elements just like those in document.body
- As far as I'm aware, XML is the only good way of storing data for javascript. I don't want to store it in javascript variables (too much multiline data with " and '). Nor do I want to build it using document.createElement("div")... etc
As someone not yet with any experience in computer science etc, please ignore my poor terminology! However, I'm not a beginner when it comes to javascript.
Here's the script concerned but I doubt it'll help you understand my problem: [URL]
I have probably a really easy question but i just cant figure it out.I want to add a <div> element every time it goes through a loop a .each in this case.I had it working in prototype before:
I have a javascript method that adds a good portion of HTML to the DOM after an AJAX request completes. It's an image uploader... so once an image uploades, I add it to the list of images along with a save and delete button. Normally when a user clicks save or delete (they are specified as classes with images called save and delete), a javascript method is called.
Problem is, when I add another image to the list along with its save and delete images, they aren't going to respond to the clicks. I know this is because I already did the
I'm trying to make a form that will generate some code for game based on what they fill out. The code will be a modification menu of sorts. They will be able to name the menus and submenus and add or remove them if they want. I will need a way to get the information they filled in for each specific menu form, so I figure giving them each a unique id would do the trick. I'm sure there is a MUCH better way to do this, but here's what I have so far:
<script> jQuery(document).ready(function() { var url='http://search.twitter.com/search.json?callback=?&q=test'; jQuery.getJSON(url,function(json){ jQuery.each(json.results,function(i,reviewa){ [Code]...
I'm baiscally trying to get some twitter feeds and the rotate them. I can get it and everything like that but for some reason the jQuery doesn't pick up the divs that I appended to the container because when I alert the div.length like this: alert(divs.length); The result is always zero. The code works fine if I can populate that value but if I don't have it in the code before hand it doesn't work. However if I add a div to the container like this:
I am after adding a mouseover (and mouseout) to a div tag, however this mouseover and mouseout will require an element id passing to it to work. Currently the tag is
The ID1 is generated when rendering the HTML and there may be multiple of these tags (each with a different ID#).I would like to add the same functionality as the first bit of code to the second, does anyknow know of this. I have been able to add mouse overs to DIV's already, however passing a variable to it I am struggling with
