I have written the following code function byId(id) { return document.getElementById(id); } function addElm(root,elm) { document.createElement(elm); if(!root) { root = document; } ...

i am having a problem with javascript and i dont know how to solve it. i am having this code function addtask(tab){ var tasktag = document.createElement( tr ); var task = document....

I m试图用符合DOM标准的耳光取代在代码中的低超字体。
