jQuery - 将text和var添加到值 [英] jQuery - add text and var to value

问题描述

我想将普通文本和jQuery值添加到输入值。

I want to add normal text and a jQuery value to an input value.

var amount = $('option:selected', this).val();
    $('.customfield').val('clicks,<?php echo $userdata['id'] ?>,' + amount +);

这就是我所拥有的，但这不起作用。有人可以向我解释，它是如何完成的？

This is what I have, but that doesn't work. Can someone explain to me, how it's done?

推荐答案

试试这个：

    $('.customfield').val('clicks,<?php echo $userdata["id"] ?>,' + amount);

//--------double quote to id as is open and   ---------^^^^
//                   closed by single quote and remove last +
