call function javascript from ASP, but with value to return

jtorta · #1 (**permalink**) 08-12-11, 12:03

Hello

I need someone to help me to be able to continue the development of a page in ASP code (not .NET)

I have a function in javascript (it's run fine), but I need call this function from ASP code by passing the value of a text variable retrieved from a database, for the function in javscript and manipulate the text and return this text with some change (CR replace with <br />, URL with anchor, ...)

I "only" need something like this (obviously does not work!)

<script>
function functionJS(value) {
//javascript code fot text manipulation
}
</script>
...
<body>
<% variable=functionJS(text); %>
<p><%= variable %></p>
</body>

If anyone can help me I would be grateful.

Thanks

I think what you need is:
(1) Change the javascript code to write the revised content to a hidden field on the form.
(2) Read the hidden field through the lhs=request("hidden_field")

OK

Thank-you AnanthaP for help me.

It's not possible because I have a undefined number of contents recovered from data base, and I don't could generate a undefined number of hidden fields for make the conversion with javascript function.

Fortunately I found a function for implementing in ASP code for make the same function than in javavascript and I call this new function for convert the text fields recover from data base.

Thanks.

can you give more details around what you are actually trying to achieve? This sounds like one of those problems where the solution is going to be quite different from the original approach taken.

What are you doing in your javascript function that can't be done in server side code?

If it has to be client side code then what does the output really look like?

One of your options might be to do something like....

Code:

<script>
function functionJS(value) {
    //javascript code fot text manipulation
    return "some changed text"
}

function reformat() {
    var contentDiv = document.getElementById("content");
    var hiddenValue= document.getElementById("serverText");
    contentDiv.innerText = reformat(hiddenValue.value);
}
</script>
...
<body onload="reformat();">
<input type="hidden" id="serverText" value="<%variable%>">
<% variable=functionJS(text); %>
<div id"content"></div>
</body>
