Add HTML Attributes And Values To This Code?
Dec 12, 2009
I'm a neophyte to Javascript, but I need it to dynamically add lines to a form. I was able to cobble together this inelegant looking code below. It adds the row when called, but there are more attributes needed for this to be correct for the application. 1) need to center the input in the TD 2)the input tags need type, size, maxsize, and value attributes added I have not been able to figure out the correct way to do this.
Also, is there a way for the value attribute to work with a PHP echo, or is there a Javascript method to display associative array values?
[Code]...
BTW is there an good online tutorial and/or reference for javascript or book(s) that you could recommend?

Let's say we have:
<div id="id2" color="brown" location="earth" iq="low"></div>
Now, we know "id". How to get all other attributes (key and values) if we do not know them ?

I'm struggling with Javascript and the DOM. Can anyone help me with
the appropriate script to get the SVG <g> element and loop through the
<text> elements, changing the value of each "y" attribute as I go.
The relevant fragment is shown below.
<g id="yaxisGroup" transform="translate(0,0.00) scale(1,1.00)">
<text x="0.00" y="24.00" font-size="18">Dog</text>
<text x="0.00" y="54.00" font-size="18">Cat</text>
<text x="0.00" y="84.00" font-size="18">Horse</text>
<text x="0.00" y="114.00" font-size="18">Bird</text>
</g>

I sometime find it useful to add my own attribute to a HTML tag so that my javascript can access those elements.
For instance, new_attribute in the following anchor tag:
<a href="#" class="someclass" new_attribute="some_value">Click Me</a>
When trying to validate this page, however, it doesn't pass. Some of the below questions likely do not make sense, but I hope you get the idea what I am looking for:Is what I am doing bad practice?Is there another way to allow javascript to specifically select just some elements and not others? Should I instead apply multiple classes to the element, and use some of the classes not to modify appearance, but to allow just them to be selected?If using custom attributes, should they somehow be defined so they pass validation?

Which is considered best practice?
<div onmouseover="doThis();">
myDiv.onmouseover = doThis;
myDiv.addEventListener("mouseover",doThis,false);
...or something else?

I have this code that when links are clicked the elements are erased. The issue that I am facing is that I want to update the order of the attributes "id" and "var_id". Basically when you remove the first or the second element to update the order. I am not very savvy with DOM so I have hard time developing that functionality. I hope you guys can help me with that.
<html>
<head>
<script>
function removeElement_e(divNum)
{
var d = document.getElementById('e');

I know that using <a href="javascript:"> and <sometag onclick=""> is evil, but in this particular situation it is quite hard to avoid it due to external powers Anyway here is the issue itself : putting javascript strings inside HTML attributes :
Code:
<button onclick="DoSomething('string')">
Everything is fine until there are single or double quotes INSIDE the 'string' value. Having a double quote inside the string, even JS escaped leads to the onclick argument value being cut :
Code:
<button onclick="DoSomething('str"ing')">
If you replace the double quote by '"' then you don't get a double quote inside DoSomething (you could always replace " by " in JS).
Similar problem if you choose to enclose the onclick argument in single quotes and happen to have a single quote JS escaped inside the string.So, is there any other way of dealing with potential presence of single AND double quotes in the 'string' value, other than replacing them before by ' and " and then replacing them back inside DoSomething ?

I am trying to make a gui for clients to edit a php page that displays html and javascript.
I want the user to be able to move html elements around and even edit it like add effects like fade in and out etc.
Then after all the changes I want to overwrite the existing php file that does this for that user. how can you make such changes and then save it to a file?
It's an html / javascript editor but using a gui instead of allowing them to directly touch the code. It would be a security risk if I allow such a thing. So I need to program a interface that would make such changes and save them to file.
Like how can you delete and add new javascript code to the file?

Within an aspx page, I have a form with asp controls (text boxes) that I'm loading within a jQuery modal popup dialog. Once the user fills out the form and the register button is clicked in the modal form, it invokes a code-behind function, which seems to be working fine. However, the problem I'm facing is in the code-behind function; none of the field values in the modal popup form are being passed to the code-behind function.I was unable to attach some snapshots directly to the post, so I uploaded it at the following urls:
