这是我的cakePHP生成的
HTML广播框和文本框脚本：
<input type="radio" id="need_staff_on_site" name="data[CaterRequest][need_staff_on_site]" value="yes" class="staff_on_site"><span>Yes</span> <input type="radio" id="need_staff_on_site" name="data[CaterRequest][need_staff_on_site]" class="staff_on_site" value="no"><span>No</span> How many staff?<input type="text" maxlength="3" id="no_of_staff" name="data[CaterRequest][staff_needed]" class="txtBoxSml2" readonly="readonly">
jquery脚本：
$(document).ready(function(){
$('.staff_on_site').click(function(){
$arr=$(this).val();
if($arr == "yes"){ $("#no_of_staff").removeAttr("readonly"); }
if($arr == "no"){ $("#no_of_staff").attr("readonly","readonly"); }
});
});
解决方法
在您的案例中,您可以编写以下jquery代码：
$(document).ready(function(){
$('.staff_on_site').click(function(){
var rBtnVal = $(this).val();
if(rBtnVal == "yes"){
$("#no_of_staff").attr("readonly",false);
}
else{
$("#no_of_staff").attr("readonly",true);
}
});
});
