如何在jQuery中制作ul和li的框图?

[英]how to make block diagram of ul and li in jquery?

我正在尝试在jQuery中制作ul和li的框图? 我找到了一种解决方案,并对其进行了修改,并得到了我想要的确切结果。 http://jsfiddle.net/5wSc5/

在这个例子中,嵌套了ul和li并带有锚标记,它显示了母猪的框图。

但是我在另一个示例中应用了这个概念(具有ul和li但没有锚标记)。它无法进行阻止。我从css中删除了所有锚标记。 http://jsfiddle.net/ZW9Pb/您能告诉我哪里错了吗?

/*Now the CSS*/
* {margin: 0; padding: 0;}

.tree ul {
    padding-top: 20px; position: relative;

    transition: all 0.5s;
    -webkit-transition: all 0.5s;
    -moz-transition: all 0.5s;
}

.tree li {
    float: left; text-align: center;
    list-style-type: none;
    position: relative;
    padding: 20px 5px 0 5px;

    transition: all 0.5s;
    -webkit-transition: all 0.5s;
    -moz-transition: all 0.5s;
}

/*We will use ::before and ::after to draw the connectors*/

.tree li::before, .tree li::after{
    content: '';
    position: absolute; top: 0; right: 50%;
    border-top: 1px solid #ccc;
    width: 50%; height: 20px;
}
.tree li::after{
    right: auto; left: 50%;
    border-left: 1px solid #ccc;
}

/*We need to remove left-right connectors from elements without 
any siblings*/
.tree li:only-child::after, .tree li:only-child::before {
    display: none;
}

/*Remove space from the top of single children*/
.tree li:only-child{ padding-top: 0;}

/*Remove left connector from first child and 
right connector from last child*/
.tree li:first-child::before, .tree li:last-child::after{
    border: 0 none;
}
/*Adding back the vertical connector to the last nodes*/
.tree li:last-child::before{
    border-right: 1px solid #ccc;
    border-radius: 0 5px 0 0;
    -webkit-border-radius: 0 5px 0 0;
    -moz-border-radius: 0 5px 0 0;
}
.tree li:first-child::after{
    border-radius: 5px 0 0 0;
    -webkit-border-radius: 5px 0 0 0;
    -moz-border-radius: 5px 0 0 0;
}

/*Time to add downward connectors from parents*/
.tree ul ul::before{
    content: '';
    position: absolute; top: 0; left: 50%;
    border-left: 1px solid #ccc;
    width: 0; height: 20px;
}

.tree li {
    border: 1px solid #ccc;
    padding: 5px 10px;
    text-decoration: none;
    color: #666;
    font-family: arial, verdana, tahoma;
    font-size: 11px;
    display: inline-block;

    border-radius: 5px;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;

    transition: all 0.5s;
    -webkit-transition: all 0.5s;
    -moz-transition: all 0.5s;
}

/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li :hover, .tree li :hover+ul li  {
    background: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}
/*Connector styles on hover*/
.tree li :hover+ul li::after, 
.tree li :hover+ul li::before, 
.tree li :hover+ul::before, 
.tree li :hover+ul ul::before{
    border-color:  #94a0b4;
}

可能是我错了,但是当您使用相同的CSS时会生成框图。因为在内部它在jstree中创建了定位标记。请检查您的HTML然后找到。
