SCRIPT438：对象不支持属性或方法的“值”

Question

我有一个从SharePoint列表创建的图形，它在Chrome中工作，但在IE 11中不工作。当我去IE 11中调试时，收到错误消息SCRIPT438: Object doesn't support property or method 'values'。我对JavaScript相当陌生。

有人可以告诉我什么可能是修复程序，或者我缺少什么

我正在使用chart.js和ajax。

<script type="text/javascript" src="/sites/carm/Shared%20Documents/Chart.min.js"></script>
<script type="text/javascript" src="/sites/carm/Shared%20Documents/jquery-1.12.4.min.js"></script>

<script type="text/javascript">

$.ajax({
        url: "/sites/carm/_api/web/lists/getbytitle('ATO%20Conditions')/items?$select=ID,Title,m4gs&$top=5000",
        type: "GET",
        headers: {
            "accept": "application/json;odata=verbose",
        },
        success: function(data) {

            if (data.d.results.length > 0) {
                var inactiveSet = {};
                var activeSet = {};
                var otherSet = {};
                var totalActive = 0;
                var totalInActive = 0;
                var totalOther = 0;

                $.each(data.d.results, function(index, item) {
                    if (item.m4gs === "Completed") {

                        } else {
                            inactiveSet[item.Title] = initZero;
                            activeSet[item.Title] = initZero;

            var otherOrdered = {};

            Object.keys(activeSet).sort().forEach(function(key) {

            var ctx = document.getElementById("myChart").getContext("2d");

            var data = {

                datasets: [{
                        label: "Active",
                        fillColor: "steelblue",
                        data: Object.values(activeOrdered)
                    },
                    {
                        label: "Completed",

                        data: Object.values(inactiveOrdered)
                    }
                ]
            };
            ....    
</script>

错误是从以下行开始的

...
var data = {
            labels: Object.keys(activeOrdered),
...

Answer 1

发生错误是因为Object.values()Internet Explorer不支持。

看到浏览器的兼容性为Object.values()

这是一种解决方法，您可以改用...

data: Object.keys(activeOrdered).map(function(key) {return activeOrdered[key];})

还有...

data: Object.keys(inactiveOrdered).map(function(key) {return inactiveOrdered[key];})
