How do you approach it? 您如何处理?
you can get the value of your last text node, this is not a problem. 您可以获取最后一个文本节点的值,这不是问题。 Unfortunately :
不幸的是:
childNodes may include text nodes, which don't support event handlers
childNodes可能包含不支持事件处理程序的文本节点
var x = document.getElementsByTagName("div")[0]; x.addEventListener("click",function(e){ console.log(e.currentTarget.childNodes[4].textContent)});
<div> target1 <span>target2</span> <span>target3</span> target4 </div>
This answer both questions you had 这回答了你的两个问题
var div = document.querySelector("div"); // get the div wrapper div.childNodes.forEach(function(node) { // loop over the nodes var text = node.textContent; // get the text if (node.nodeName=="#text" && text.trim()!="") { // if text and not empty var span = document.createElement("span"); // wrap in a span span.textContent = node.textContent.trim(); node = div.replaceChild(span,node); } }); div.onclick=function(e) { console.log(e.target.textContent); }
span { color:red }
<div> target1 <span>target2</span> <span>target3</span> target4 </div>
