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
