IE 11 AngularJS错误-对象不支持属性或方法“来自" [英] IE 11 AngularJS error - Object doesn't support property or method 'from'

问题描述

在我的JavaScript中，我有一个函数detectEnvironmentAndGetLEAndDepot()，该函数通过HTML称为onload.我正在使用wicket，需要获取后端保存的值，因此将它们发射到屏幕上，将其隐藏，然后从我的JS中搜索<span>值以获取name值，例如if(v.getAttribute('name') === 'LE'){do stuff}或if(v.getAttribute('name') === 'depot'){do stuff}(我确定这不是最优雅的解决方案，但我需要一个快速的解决方案！).然后在函数detectEnvironmentAndGetLEAndDepot()中，我进行了一些格式化等操作，以便使数据可用.

In my JavaScript I have a function detectEnvironmentAndGetLEAndDepot() which is called onload via HTML. I'm working with wicket, and need to take values held in the back-end, so I fire them to the screen, hide them, and search the <span> values from my JS for the name value, for example if(v.getAttribute('name') === 'LE'){do stuff} or if(v.getAttribute('name') === 'depot'){do stuff} (I'm sure not the most elegant solution, but I needed a quick one!). Then within the function detectEnvironmentAndGetLEAndDepot() I do a bit of formatting etc so the data is usable.

detectEnvironmentAndGetLEAndDepot()函数(很长，只有相关部分)-

detectEnvironmentAndGetLEAndDepot() function (quite long, only relevant part) -

detectEnvironmentAndGetLEAndDepot = function() {

    Array.from(document.getElementsByTagName('span')).forEach(function(v) {

//Search name tag for particular names, then do formatting
}

当我在IE11中打开此文件时，我在弹出式窗口SCRIPT438: Object doesn't support property or method 'from'中收到错误，该消息与上述方法的第一行-Array类有关.非常感谢.

When I open this in IE11 I get the error in a popup SCRIPT438: Object doesn't support property or method 'from' which is related to the first line of the method above - the Array class. Help much appreciated.

推荐答案

由于IE不支持Array.from方法，因此您可以尝试使用:

As Array.from method is not supported by IE, you can try to use:

[].slice.call(document.getElementsByTagName('span')).forEach(function(v) {});

这不需要使用任何第三方库.

This doesn't require usage of any 3rd party libraries.
