如何更改javascript中的元素

Question

This label doesn't have an id/class. How can I change the element from "Status" to another word in JS?:

 <label form="mpp-gallery-status">Status</label>

Answer 1

You can use querySelector / querySelectorAll / getElementsByTagName to get the label, but if you don't have any sort of identifying characteristic besides the contents of the tag then you're gonna have to do a bit of qualification on the selector:

 var labels = document.getElementsByTagName("label"); for (var i = 0; i < labels.length; i++) { var ele = labels[i]; if (ele.getAttribute("form") == "mpp-gallery-status" && ele.innerHTML == "Status") ele.innerHTML = "Another word"; }

 <label form='mpp-gallery-status'>Test</label> <br /> <label form='mpp-gallery-status'>Status</label>
