About jquery Implementing a CheckBox Select All only once

2. This code has only one time to select all, all the effects of the third click Checkall will not have any effect
4. $ ("#checkall"). Click (function () {
6. $ (' input[name= ' Check "]). attr (" Checked ",this.checked);
8. });
10. Use prop to achieve the desired results per click
12. $ ("#checkall"). Click (function () {
14. $ (' input[name= ' Check "]). Prop (" checked ",this.checked);
16. });
18. Because checked is an intrinsic property of a checkbox, using attr is a direct delete setting property which may cause the browser to generate an error that JS cannot continue execution
