[英]Not able to push elements from one array to another array in jquery
I have a line of code which is trying to push elements from one array to another array. 我有一行代码试图将元素从一个数组推到另一个数组。
var criArray=[];
jQuery('form').find(':input[name=criteria]').toArray().each(
function(val) {
criArray.push(jQuery(val).val())
}
);
When I load the page, in browser console, I am getting below error at this line. 当我加载页面时,在浏览器控制台中,我在此行得到错误提示。
Uncaught TypeError: undefined is not a function.
I am clueless of ways to push elements to array as I tried many answers from my google search. 当我尝试谷歌搜索中的许多答案时,我不知道将元素推送到数组的方法。 Can someone help me on this?
有人可以帮我吗?
You can use .map() to do this 您可以使用.map()执行此操作
var criArray = jQuery('form').find(':input[name=criteria]').map(function () {
return jQuery(this).val();
}).get();
The problem is .toArray() returns an array object which does not have the .each()
method, you could use .forEach() instead 问题是.toArray()返回一个没有
.each()
方法的数组对象,可以改用.forEach()
