.width()错误$(...)[0] .width不是函数吗? [英] .width() giving error $(...)[0].width is not a function?
问题描述
我有一张桌子,我试图找到桌子上每个td的宽度.我尝试了以下各种变体:$("td")[0].width()
,但是它们都不起作用,每次都会出现错误:"Uncaught TypeError: $(...)[0].width is not a function"
.
我先导入jQuery,再导入其他JS文件,( https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js ),而我使用的是.width()而不是.width.>
有什么想法吗?
$("td")[0]
是DOM元素,而不是jquery对象.只需将其包装为jquery $($("td")[0]).width()
您需要获取每个td
的宽度,以便可以使用
$.each('td', function() {
var currentTDWidth = $(this).width(); // more code here
});
I have a table, and I'm trying to find the width of each td in the table. I've tried all kinds of variations of: $("td")[0].width()
, but none of them work, getting an error of: "Uncaught TypeError: $(...)[0].width is not a function"
everytime.
I'm importing jQuery first, before my other JS files, (https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js), and I'm using .width() not .width.
Any ideas?
$("td")[0]
is a DOM element not a jquery object. Simply wrap it as jquery $($("td")[0]).width()
You need to get width of each td
so you could use something like
$.each('td', function() {
var currentTDWidth = $(this).width(); // more code here
});
