数组在formar“item1，item2”中具有值。我希望它是[“item1”，“item2”]。我该怎么办？

 console.log(jQuery("#tickets-expanded input:checkbox[name='ids[]']:checked"));
        jQuery("#tickets-expanded input:checkbox[name='ids[]']:checked").each(function() {
           selected.push(jQuery(this).val());
        });
        alert(selected);

        jQuery("#ids").val(selected);

This is my code. Selected array contains elements in the format "2,1". I want it to be ["2","1"]. What should I do?

5 个解决方案

#1

Consider the code:

考虑一下代码：

var a = "item1,item2,item3";

a = a.split(",");

console.log( a );

Output will be:

输出将是：

["item1","item2","item3"]

Now you can apply this technique on your code at the end. The string you are getting can be split and you will get the array.

现在，您可以在最后将代码应用于代码。您获得的字符串可以拆分，您将获得该数组。

Edit: You have multiple id elements? So you can also split data among them. Each will contain a value

编辑：你有多个id元素？所以你也可以在它们之间分割数据。每个都包含一个值

Thats what its toString() returns, if you want a different format construct it manually:

这就是它的toString（）返回的内容，如果你想要一个不同的格式手动构造它：

str = "[\"" + selected.join("\",\"") + "\"]";

#3

selected = '[' + selected + ']';

#4

'5,6,7'.split(',')

Try this to get an array of selected checkboxes

试试这个以获得一系列选中的复选框

var values = $("#tickets-expanded input:checkbox[name='ids[]']:checked").map(function () {
  return this.value;
}).get();
