jquery – 具有id的div内的多个标签的选择器

在jQuery中,如何为#con中的标签h1,h2,h3和p构建选择器？

像$(‘#con h1,#con h2,#con h3,#con p’)但不重复#con

解决方法

您可以执行以下任何操作：

$("#con h1,#con p")   // your original

$("h1,h3,p",$("#con"))            // pass jQuery object in as context

$("h1,"#con")               // pass selector in as context

$("#con").find("h1,p")          // do what jQuery ultimately does 
                                         // in the end when passing context
                                         // as jQuery or as string selector

I’ve created a nice little jsFiddle that demos all of this.
