Editor to share with you how jquery can control checkbox with one click to select all, anti-election or none, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The jquery attr () method can be problematic in getting the checked of the tag, so the prop () method is used.

Hml's checkbox does not add name, only div nesting.

/ / Select all $('# allChecked') .change (function () {$('# box'). Children (': checkbox') .prop ('checked',$ (this) .is (': checked')? true:false);}) / / invert $('# invertChecked') .change (function () {if ($(this) .is (': checked')) {$('# box'). Children (': checkbox') .each (function () {$(this) .prop ('checked',$ (this) .is (': checked')? false:true);}}) / / one button controls selecting all, inverting, and deselecting $('# orChecked') .change (function () {if ($(this) .is (': checked')) {var box = $('# box'). Children (': checkbox'); if (box.length==box.filter (': not (: checked)') .length) {/ / check box length is the same as the number of unselected check boxes-> all, .not (': checked'). Length is also possible. $('# box'). Children (': checkbox'). Prop ('checked',true);} else {/ / if there are selected numbers,-> invert $(' # box'). Children (': checkbox') .each (function () {$(this) .prop ('checked',$ (this) .is (': checked')? false:true);}) } else {$('# box') .children (': checkbox') .prop ('checked',false); / / if the control key is unchecked, the remaining checkbox will also be unchecked}}); watermelon, mango, orange, mangosteen, strawberry, dragon fruit
