如何使用javascript包含struts html标签? [英] How to use javascript to include struts html tag?

问题描述

我有一个复选框和一个文本框. 我已经使用了struts标记和

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

现在，我需要验证是否选中了该复选框，我应该将文本框变灰(禁用).如果未选中，则文本框将保留电话号码.

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.

我确实喜欢这个，我在复选框的单击处调用了Java脚本，并检查了是否基于Wheater复选框ix的innerHtml.

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){ document.getElementById("line1").readonly ="true"; } 别的{ document.getElementById("line1").readonly ="false"; }

var status_check=document.getElementById("line1Checked").checked; if(status_check==true){ document.getElementById("line1").readonly="true"; } else{ document.getElementById("line1").readonly="false"; }

如果选中该复选框，则我会将文本框设置为只读. 这是文本框的定义方式，

I shud make the text box readonly if the check box is selected. This is how the text box is defiened,

请提出建议.

OK - now it's easier to understand - thanks. 1. make sure that use the styleId - attribute within your for the input-field. To set this input field readonly your javascript code should do:

document.getElementById("line1").setAttribute("readonly","true");
