[英]How to find a particular grand parent by Id and get value of its particular children by certain class using jQuery
我有一个动态div
<div class="illustartionWrap" id="illustartionWrapId">
<div class="illusList illusListTop" id="illusList_heading">
<span class="fileName">File Name</span>
<span class="fileDesc">Description</span>
<span class="fileSize">File Size</span>
<span class="fileDownload">Download</span>
</div>
<div class="clear"></div>
<div class="illusList">
<span class="fileName">fileTitle</span>
<span class="fileDesc">fileDesc</span>
<span class="fileSize">1.18 MB</span>
<span class="fileDownload">
<a href="http://myfile/file.txt">
<img src="/sites/all/themes/petheme/images/myimage.png">
</a>
<a href="#">
<img id="illFile_6" class="illDeleteFile" src="/sites/all/themes/petheme/images/icons/deleteButton.png">//clicking it to delete the file from db
</a>
</span>
</div>
</div>
如何获取此删除按钮的父对象并找到filetitle类以获取文件的标题。
下面是我写的点击处理程序
/**delete function for my page**/
jQuery(".illDeleteFile").on("click", function() {
var illDeleteId = jQuery(this).attr("id").split("_");
var illFileTitle = jQuery(this).parent("#illusList").children(".fileName").val();
alert (illFileTitle);
});
我用jQuery Parent(),Parents()和children()以及find()进行了检查,但是我得到的大多是未定义的,而且没有标题。
如何实现呢?

您将要使用:
var illFileTitle = jQuery(this).closest(".illusList").find(".fileName").text();
alert(illFileTitle);
看到这个
jQuery(".illDeleteFile").on("click", function() {
var illFileTitle =jQuery(this).closest(".illusList").find(".fileName").html();
alert (illFileTitle);
});
