How To Avoid The Execution Of A Function At The Time Of Defining.

Mar 18, 2007

How to avoid the execution of a function at the time of defining.

Here i am giving the details.

I am creating the following div container through DOM.

<div id="content">
<a href="#" onclick="displayDiv('content')" Click</a>
</div>

The Code is:

var category_list = document.getElementById('category_list');
var dom_div = document.createElement('div');
dom_div.id = 'content'
val = document.createTextNode('Click');
category_list.appendChild(dom_div);

The displayDiv Funcion

function displayDiv()
{
dv = document.getElementById('content'); //Here is the error.
}

The Problem is when the following script:

is executed it is calling the function displayDiv(name)
Here we have the code
document.getElementById('content');
which throws the error.

The reason is the div container is not yet created.

What I need is the function should be called only on the click event. It should not be called while I define it to the Click Event. (ie it should not be called at the time of defining)
How to achieve this.

I have an array in which each element is a long string of various values separated by a particular character.I want to be able to search the array using the first value of each element to get the index.I cannot see how to do this so I have started to create a function for this.I want to take the original array, split out the value into another array and search the new array.I can then use the index returned to retrieve the full string from the original array.However I am having a problem when trying to set the new array and I do not know enough JS to understand what is going wrong.Here is the code:

Code:
<script type="text/javascript">

JQuery :: Determine The Position (index) Of A Particular Textbox In A Textbox Array?

Jan 18, 2011

I have two textbox columnsof equal length they are accessed in the following manner:

taborder 1
taborder 2 taborder 3 taborder 4 taborder 5 taborder 6 taborder 7 taborder 8

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:

\$('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.
