A Jsp plus Javascript query

j.gohel · 03-16-2006, 02:54 AM

Hi,

I am having the following simple jsp page.:

Code:


    <HTML>
<HEAD>
<TITLE>Hyperlink Javascript Test </TITLE>
<script type = "text/javascript">
function testLink(val)
{	
	document.write(val);
}
</script>
</HEAD>
<BODY>
<form name = "test_link">
<table>	
	<%
		for(int k = 0; k < 5; k++)
		{
			String h_Nm = "hName"+k;
			String a_name = "nm"+k;
	%>
			<tr>
				<td>
					<input type = "button" name = "<%= h_Nm %>" value ="<%= a_name %>" onClick = "testLink(this.value)">					
				</td>
			<tr>
	<%
		}
	%>
</table>
</form>
</BODY>
</HTML>

O running this page i will get 5 buttons with their corresponding dynamic values . & on clicking the buttons i will get their respective values displayed.

But i want to do is i want a hyperlink instead of button with same label ,not different labels which i am getting at present which are the values i am getting dynamically, for each of the five hyperlinks but when i click on that hyperlink i should get the dynamic value i am providing at present for the button using javascript.

So please tell how to do this.

Thanks,
Jignesh

You're problem is here:

Code:

String h_Nm = "hName"+k;
String a_name = "nm"+k;

"k" is assigned in the 'for' loop, and each time through the loop is incremented by one. As a result, h_Nm and a_name are going to reflect that. If you want one to stay the same, then you can't alter it each time through the loop.

Hi thanks for the reply.

Sorry i was not able to explain my query properly.

What i want is a HYPERLINK instead of a BUTTON.And as per my code when i click on the hyperlink i should get some unique value associated with that hyperlink & that unique value i want to provide using JSP .So that when i click on a particular hyperlink the unique value provided by me to the hyperlink gets displayed in the browser through my javascript function.So

how to acheive this??
Thanks

Ah, it's not a JSP problem then, but an HTML and Javascript problem.

You're looking for

Code:

<a href="javascript:void(0)" onClick="testLink('<%= a_name %>')"><%= h_Nm %></a>

"javascript:void(0)" will allow you to execute Javascript using the anchor tag by basically telling the browser to not follow the hyperlink like it usually would. You can then use the "onClick" or other attribute.

Because you're handing the value directly to the function, you'll need to quote it, but you don't want to break out of the quote used by the "onClick", so you need to use the single quote.

Re-arraign to taste.
