<script>
$(document).ready(function(){
<!-- radio的禁用 -->
var input = $("#appDIV").find("input:radio");
input.attr("disabled","disabled");
input.each(function(){
if($(this).val()==2){
$(this).attr("checked",true);
}
});
<!-- checkbox的禁用 -->
var checkbox = $("#ce").find("input:checkbox");
checkbox.attr("disabled","disabled");
checkbox.each(function(){
if($(this).val()=="Monthly"){
$(this).attr("checked",true);
}
});
<!-- select的禁用方法一 -->
$("#selectItem option:disabled").css('color', '#CCC');
$('#selectItem').change(function(){
if(this[this.selectedIndex].disabled){
this.selectedIndex = this.s||0;
}else{
this.s = this.selectedIndex||0;
}
});
<!-- select的禁用方法二 -->
$("#selectItem").attr("disabled","disabled");
});
//以上方法都可以实现
$(this).find("select,:radio,:checkbox").attr("disabled", "disabled"); 这样也可以直接实现！
