The example in this article describes the method of deleting child nodes created by javascript. Share it with everyone for your reference. The details are as follows:
I don’t know how to delete the node created by js. . . It took a lot of time
for(var i = 0; i < jsonList.length; i++ ){ var li_button = document.createElement("li"); li_button.className = "button"; var li_button_a = document.createElement("a"); li_button_a.id = jsonList[i]._id; var li_button_text = document.createTextNode(jsonList[i].projectName); li_button_a.appendChild(li_button_text); li_button.appendChild(li_button_a); ul_level2.appendChild(li_button); }
Later I found out that the node is actually
ul_level2.innerHTML = '';InnerHTML ='' content, as long as it is set to empty, the child nodes can be cleared.
I hope this article will be helpful to everyone’s JavaScript programming design.
