节点不能在层次结构的特定点插入“代码：” 3

Question

嘿，这又是我一个关于jQuery的问题和网格布局我犯了一个PHP带开关，我插入代码模板是这

<div id="wrapper">

<div id="grid">
<div class="box"><img src="img/an_005_BUR_thebeat.jpg" width="310px" height="438px" />3 index</div>
<div class="box"><img src="img/an_014_GUE_homme_a.jpg" width="310px" height="404px" />4 Culture</div>
<div class="box"><img src="img/an_044_BVL_springmotiv.jpg" width="310px" height="310px" />5 Pharma</div>
<div class="box"><img src="img/an_039_AN_diskette.jpg" width="310px" height="465px" />6 Pharma IT</div>
<div class="box"><img width="310px" height="100px" />7 Culture</div>
<div class="box"><img width="310px" height="120px" />8 Cosmetics</div>
<div class="box"><img width="310px" height="400px" />9 IT</div>
<div class="box"><img width="310px" height="400px" />10 Culture</div>
<div class="box"><img width="310px" height="400px" />11 IT</div>
<div class="box"><img width="310px" height="400px" />12 Culture</div>
</div>

</div>
    <script type="text/javascript">

    $(document).ready(function(){

        $('#grid').gridLayout('.box', {col_width: 340, min_cols: 2});
        // options - (values above are the defaults)
        // col_width: the width of each grid block
        // min_cols: the minimum number of cols on the page (reducing browser width below this will not decrease number of columns). Set to your largest block (3 = block spans 3 columns)

        // gridLayout.placeAtEnd() - for placing a block at bottom right of grid
        var final_block = $('');
        $('#grid').gridLayout.placeAtEnd( final_block );

        // gridchange event fires when window resize forces a grid refresh
        $('#grid').bind( "gridchange", function(e){
            console.log('gridchange event fired');
            // reposition the final block
            $('#grid').gridLayout.placeAtEnd( final_block );
        });

        // this forces a redraw of grid
        $('body').gridLayout.refresh();

        // returns heights of each column
        console.log( 'gridLayout.info():', $('#grid').gridLayout.info() );
    });

</script>

在jQuery脚本和插件被装载在首部。当我尝试运行此。萤火虫告诉我：

“3”

码“节点不能在分层结构中的指定点插入的”

难道有人知道如何解决这一问题？

Answer 1

我敢肯定你的错误是与以下。什么是$（ ''）！

var final_block = $('');
$('#grid').gridLayout.placeAtEnd( final_block ); 

它的工作原理，如果我说

var final_block = $('<div />');
$('#grid').gridLayout.placeAtEnd( final_block );

Answer 2

显示（在Firebug）的错误信息，如果你有不正确的HTML在$（）构造函数，以及当您尝试一个节点追加到自身，e.g：

$div = $('<div />');
$div.append($div);
