我正在尝试在复选框的检查/取消检查事件中替换div的内容。
HTML:
<div class="checks">
<input type="checkbox" class="section-1" value="section-1">check-1
<input type="checkbox" class="section-2" value="section-2">check-2
<input type="checkbox" class="section-3" value="section-3">check-3
<input type="checkbox" class="section-4" value="section-4">check-4
<input type="checkbox" class="section-5" value="section-5">check-5
<input type="checkbox" class="section-6" value="section-6">check-6
<input type="checkbox" class="section-7" value="section-7">check-7
</div><br><br>
<div class="divs">
<div class="section-1">
<div class="content-1">
div-1
</div>
</div>
<div class="section-2">
<div class="content-2">
div-2
</div>
</div>
<div class="section-3">
<div class="content-3">
div-3
</div>
</div>
<div class="section-4">
<div class="content-4">
div-4
</div>
</div>
<div class="section-5">
<div class="content-5">
div-5
</div>
</div>
<div class="section-6">
<div class="content-6">
div-6
</div>
</div>
<div class="section-7">
<div class="content-7">
div-7
</div>
</div>
</div>
<div class="divs-back" style="display: none">
<div class="section-1">
<div class="content-1">
div-1
</div>
</div>
<div class="section-2">
<div class="content-2">
div-2
</div>
</div>
<div class="section-3">
<div class="content-3">
div-3
</div>
</div>
<div class="section-4">
<div class="content-4">
div-4
</div>
</div>
<div class="section-5">
<div class="content-5">
div-5
</div>
</div>
<div class="section-6">
<div class="content-6">
div-6
</div>
</div>
<div class="section-7">
<div class="content-7">
div-7
</div>
</div>
</div>
jquery的:
$(":checkbox:lt(7)").prop("checked", true);
var array = ["section-1", "section-2", "section-3", "section-4", "section-5", "section-6", "section-7"];
var unArray = [];
var unChecked = 0;
$('input[type="checkbox"]').click(function () {
if ($(this).prop('checked')) {
// Add the new element if checked:
if (array.indexOf($(this).val()) < 0) {
array.push($(this).val());
unChecked = unArray.slice(-1)[0];
unArray.splice(-1, 1);
}
} else {
// Remove the element if unchecked:
if (array.indexOf($(this).val()) >= 0) {
array.splice(array.indexOf($(this).val()), 1);
unArray.push($(this).val());
unChecked = 0;
}
}
showHideDiv($(this).val(), unChecked);
console.log(array);
console.log(unArray);
});
function showHideDiv(value, unCheked) {
console.log(unCheked);
if (unCheked != '0') {
$('.divs').find("." + unCheked).html($('.divs-back').find("." + value).html());
} else {
$('.divs').find("." + value).html('');
}
}
首次尝试成功替换内容。但是在第二次尝试时,div内容的位置会发生变化,从而无法获得所需的输出。

修改 实际上,我不想隐藏节目。我想替换上一个未选中部分的div内容。当我取消选中Section-1,Section-2,Section-3时,如果我们检查section-1,那么它应该放在Section-3的DIV中。

为什么您的代码无效?
问题是你在推动元素。 push()方法将新项添加到数组的末尾,并返回新的长度。
//的Array.push($(本).VAL());
删除此行
您必须做出改变。
$('input[type="checkbox"]').click(function() {
var unchkdArray = [];
var chkdArrray = [];
$('input[type="checkbox"]').map(function(){
if ($(this).is(':checked')) {
chkdArrray.push($(this).val())
} else {
unchkdArray.push($(this).val())
}
});
var selected = $(this).val()
if ($(this).is(':checked')) {
$('div.' + selected).show()
} else {
$('div.' + selected).hide()
}
});

试试这个......
$(":checkbox:lt(7)").prop("checked", true);
var array = ["section-1", "section-2", "section-3", "section-4", "section-5", "section-6", "section-7"];
var unArray = [];
var unChecked = 0;
$('input[type="checkbox"]').click(function () {
console.log($(this)['context']['className']);
$( ".divs ."+$(this)['context']['className'] ).toggleClass( "hide" )
});
