I have a check box and a text box. I have used struts tags and

Now i need to validate that if the check box is checked, i should gray out (disable) the text box. If it is unchecked the text box shold take phone numbers.

I did lik this, i called a java script on click of check box and did a innerHtml based on wheather checkbox ix checked or not.

var status_check=document.getElementById("line1Checked").checked; if(status_check==true){ text=""; } else{ text=""; } alert(text); document.getElementById("line1").innerHTML=text;

this works but if i use,

var status_check=document.getElementById("line1Checked").checked; if(status_check==true){ ";
} else{ "; } alert(text); document.getElementById("line1").innerHTML=text;

It doesn work. All i know is struts tags execute at server. is there any possiblity to achieve this?

Please help me.
