请有人告诉我如何设置全部检查并取消选中所有当我在所有检查后逐个检查单个复选框时,上面检查并取消选中所有选中,这就是他被检查的原因。这是我目前正在使用的代码:
$(document).ready(function(){
$('.checkall').click(function(){
$('input:checkbox').prop('checked',true);
$('.uncheckall').prop('checked',false);
console.log(checkedValues);
});
$('.uncheckall').click(function(){
$('input:checkbox').prop('checked',false);
$(this).prop('checked',true);
});
$('.single').on('click',function(){
if($('.single:checked').length == $('.single').length){
$('.checkall').prop('checked',true);
$('.uncheckall').prop('checked',true);
}else{
$('.checkall').prop('checked',false);
$('.uncheckall').prop('checked',false);
}
});
});

function toggle(source) {
checkboxes = document.getElementsByName('foo');
for(var i=0, n=checkboxes.length;i<n;i++) {
checkboxes[i].checked = source.checked;
}
}

<script language="JavaScript">
function toggle(source) {
checkboxes = document.getElementsByName('foo');
for(var checkbox in checkboxes)
checkbox.checked = source.checked;
}

$(".checkall").on("click",function(){

});
$(".uncheckall").on("click",function(){

要更改标签以全部选中/取消选中全部切换: 看到这个JSFiddle并实现它我仍然在工作,并且很快就会在这篇文章中完成代码并点击这里! 这是Fiddle嵌入:
<script async src="//jsfiddle.net/kq958k3s/147/embed/result/"></script>

谢谢!
