Question

在页面加载时，我想用div包装标题范围并将其移动到相关主体div的前面。即，将hApplicant1 span移到tabApplicant1 div等的前面

如何编写jQuery来完成此任务？谢谢！

假设：

<div>
            <div id="header">
                <span id="hDummy"></span>
                <span id="hApplicant1">James Smith</span>
                <span id="hApplicant2">John Doe</span>
                <span id="hApplicant3"></span>
                <span id="hApplicant4"></span>
            </div>
            <div id="body">
                <div id="tabApplicant1">...</div>
                <div id="tabApplicant2">...</div>
            </div>
</div>
<div>
            <div id="header2">
                <span id="h2Dummy"></span>
                <span id="h2Applicant1">Black Smith</span>
                <span id="h2Applicant2">Shoe Maker</span>
                <span id="h2Applicant3"></span>
                <span id="h2Applicant4"></span>
            </div>
            <div id="body2">
                <div id="tab2Applicant1">...</div>
                <div id="tab2Applicant2">...</div>
            </div>
</div>

结果应该是这样的：

<div>
            <div id="header">
                <span id="hDummy"></span>
                <span id="hApplicant3"></span>
                <span id="hApplicant4"></span>
            </div>
            <div id="body">
                <div><span id="hApplicant1">James Smith</span></div>
                <div id="tabApplicant1">...</div>
                <div><span id="hApplicant2">John Doe</span><div>
                <div id="tabApplicant2">...</div>
            </div>
</div>
<div>
            <div id="header2">
                <span id="h2Dummy"></span>
                <span id="h2Applicant3"></span>
                <span id="h2Applicant4"></span>
            </div>
            <div id="body2">
                <div><span id="h2Applicant1">Black Smith</span></div>
                <div id="tab2Applicant1">...</div>
                <div><span id="h2Applicant2">Shoe Maker</span><div>
                <div id="tab2Applicant2">...</div>
            </div>
</div>

Answer 1

var $bodyDiv = $('#body');

$('#header span[id^=hApplicant]').each(function(){
    $bodyDiv.find('div[id=' + $(this).attr('id').replace('h', 'tab') + ']').before( $(this).wrap('<div />').parent() );
});

这可以进一步简化（和优化），但它应该让你开始走上正确的轨道。

修改

这可以重复：

var $bodyDiv = $('#body'), $bodyDiv2 = $('#body2'); $('#header span[id^=hApplicant]').each(function(){ $bodyDiv.find('div[id=' + $(this).attr('id').replace('h', 'tab') + ']').before( $(this).wrap('<div />').parent() ); }); $('#header2 span[id^=h2Applicant]').each(function(){ $bodyDiv2.find('div[id=' + $(this).attr('id').replace('h', 'tab') + ']').before( $(this).wrap('<div />').parent() ); });

Answer 2

    $('#header span').each(function() {
        var that = $(this);
        var thatId = that.attr('id');
        var bodyDiv = $('#body #' + thatId.replace('h', 'tab'));
        if (bodyDiv.length)
            that.insertBefore(bodyDiv).wrap('<div/>');
    });
