在jQuery中,如何使用特定的选择器获取元素的任意级父元素?我不确切知道它在哪里,我只知道它存在于当前元素上方的DOM中。这是我想要的一个原始例子:
<div id="world" >
<div class="forest" id="some_random_forest">
<div id="groove">
<div id="oak_tree">
<div id="a_branch"></div>
</div>
</div>
</div>
<div id="south_america">
<div class="forest" id="rain_forest">
<div id="jungle_tree"></div>
</div>
</div>
<div id="europe">
<div id="germany">
<div class="forest" id="black_forest">
<div id="pine_tree">
<div id="a_pine_needle"></div>
<div id="cute_squirrel"></div>
</div>
</div>
</div>
</div>
</div>
<script type="application/javascript">
function getParentForest(subject){
// return the closest div with the class forest to the subject element.
}
// So this would be the return values of the following function calls
getParentForest("#a_branch"); // returns $("#some_random_forest")
getParentForest("#jungle_tree"); // returns $("#rain_forest")
getParentForest("#a_pine_needle"); // returns $("#black_forest")
getParentForest("#cute_squirrel"); // returns $("#black_forest")
</script>

你正在寻找这个:
$('#a_branch').closest('.forest');
