Question

How do I set the value of the href based on a variable value.
As of now, I have the follwing code:

<a href="javascript:clearDate('txtDueDate');"

Waht I need is shown below. I want the href value to be disabled if udisable is true.

var udisable = '<%=dueDateDisabled %>';
if (udisable == "false")
         <a href="javascript:clearDate('txtDueDate');"
      else
          <a href="javascript:void(0);"

Answer 1

Try

<a href="javascript:if (udisable == "false) {clearDate('txtDueDate');}"/>

or even better: Create your own function encapsulating this:

// In some JavaScript file:
function clearDate2(dateString) {
    if (udisable == "false") {
        clearDate(datestring);
    }   
}

<a href="javascript:clearDate2('txtDueDate');"/>
