- }
- //反选
- function unAllSelect(){
- $("input[name=‘fruit‘]").removeAttr("checked");
- $("input[name=‘select‘]").removeAttr("checked");
- }
- //单选
- $("#allBook").click(function(){
- if(this.checked){
- // $("input[name=‘book‘]").attr("checked", true);
- $("input[name=‘book‘]").prop("checked", "checked");
- }else{
- // $("input[name=‘book‘]").attr("checked", false);
- $("input[name=‘book‘]").removeAttr("checked");
- }
- });
- </script>
- </div>
- </body>
- </html>
在实践中碰到一个问题——check全选失效。解决办法,使用prop方法代替attr。
- $("input[name=‘book‘]").attr("checked", "checked");
- $("input[name=‘book‘]").prop("checked", "checked");
这或许是和jQuery版本有关。
