事业部生产NaN [英] Division produces NaN

问题描述

我正在尝试将变量 number 除以 100 并得到 NaN 。我是jQuery的新手，有人可以帮助我了解我在做什么吗？

I'm trying to divide the variable number by 100 and get NaN. I'm new to jQuery, can anyone help me to understand what I'm doing wrong?

$.each(data.products, function (i, data) {

    var div_data = "<p>" + data.title + "<br/>" + data.description + "</p>";

    div_data += '<img src="' + data.imageUrl + '" title="Loading..." alt="Loading...">';
    div_data += '<p><a href="' + data.url + '">Buy</a></p>';

    $(div_data).appendTo("#testjson");

    number = '<div class="number">' + data.price + '</div>';
    $('#myElement').text((number / 100));

});

推荐答案

首先要设置数字到字符串：

number = '<div class="number">'+ data.price + '</div>';

然后，您将字符串除以 100

Then you are dividing that string by 100

在JavaScript中导致 NaN ，是 Not a Number 的缩写。在规范中指定。

In JavaScript that results in NaN which is short for Not a Number . This is specified in the spec.

可能的解决方案是将数字本身除以100，而不是HTML字符串，例如：

A possible solution could be to divide the number itself by 100, and not the HTML string, for example:

var number = data.price/100;
$('#myElement').text(number);

这不会将嵌套的div附加到您的 #myElement 。

This would not attach a nested div to your #myElement though.
