我正在编写一个工作项目，当页面加载时，它将通过ajax查询抓取一个页面，单击按钮它将抓取另一个页面。我已经检查了 ajax 的语法，似乎可以正常工作，在 Chrome 和 FireFox 中测试了相同的代码。
来自 ie 开发工具的错误如下:
SCRIPT1010: Expected identifier
File: admin, Line: 40, Column: 15
我只是不明白为什么它在没有代码的地方给我一个错误:
</head>
<body class="default-bg">
<div class="container">
<div class="container-fluid">
<div id="header">
<div class="jumbotron card-primary">
<!--ie errors here--> <h2 class="text-center">Administration Panel</h2>
</div>
</div>
</div>
</div>
...
<script>
$(document).ready(function(){
$.ajaxSetup({ cache: false });
$("button#content-approval-button").addClass('active-btn');
getPage('cap');
});
function getPage(pageToGet){
$.ajax({
url:"../includes/scripts/php/actions/pages.php",
type:"POST",
cache:false,
data:"&page=" + pageToGet,
success:function(r){
$('#page-content').html(r);
},
error:function(r){
alert("failed");
}
});
}
</script>
问题是，当页面加载并且您尝试单击内置 JS 的内容并且 IE 开发工具很糟糕时，它会引发更大、更讨厌的配合。 这是页面中的脚本标记我尝试加载功能失败，我觉得这是由于 1010 错误
<script>
var output="";
var md=window.markdownit({
html:true,
typographer:true,
xhtmlout:true,
breaks:true,
linkify:true
});
md.use(window.markdownitEmoji);
md.use(window.markdownItAttrs);
md.use(window.markdownitAbbr);
md.use(window.markdownitDeflist);
md.use(window.markdownitIns);
md.use(window.markdownitMark);
md.use(window.markdownitSub);
md.use(window.markdownitSup);
md.use(window.markdownitMultilineTbl);
md.renderer.rules.table_open = function(tokens, idx) {
return '<table class="table table-striped">';
};
function parseMarkDown(){
var input = $("#input").val();
var semiSanitized = input.replace(/javascript:/igm," javascript code is disabled ");
//the code sanitation will finish on the sever side with removal of script tags.
//client side it "sanitizes the page as well as input... thus making the page break.
output = md.render(semiSanitized);
$('#output').html(output);
}
function updateTitle(){
var i = $('#title').val();
var semiSanitized = i.replace(/javascript:/igm," javascript code is disabled ");
$('#c-title').text(i);
}
function insertByButton(startEle,endEle){
var inV = document.getElementById('input');
const {value, selectionStart, selectionEnd} = inV;
const beforeSelection = value.substring(0, selectionStart);
const selection = value.substring(selectionStart, selectionEnd);
const afterSelection = value.substring(selectionEnd);
inV.value = beforeSelection + startEle + selection.trim() + endEle + afterSelection;
parseMarkDown();
inV.focus();
if (selectionEnd == selectionStart){
var i = beforeSelection + startEle;
inV.setSelectionRange(i.length,i.length);
}else{
inV.setSelectionRange(selectionEnd,selectionEnd);
}
}
function buildPageTemplate(){
var inV = document.getElementById('input');
var h = "some proprietary text\n";
h += "# "+$("#title").val()+'{class="jumbotron card-primary card-shadow card-bottom-spacer-md text-center" id="doc-title" title="'+$('#title').val()+'"}\n';
inV.value = "";
inV.value = h;
parseMarkDown();
}
下面是一些应该将文本插入文本区域的按钮...

正如之前提到的，所有这些代码在其他浏览器中都运行良好，但由于该公司主要使用 IE11，我被迫为其开发......对可能出现问题的任何建议？
最佳答案
您的问题在这里:
const {value, selectionStart, selectionEnd} = inV;
您不能将值破坏为变量列表。任何版本的 IE 都不支持它。 请参阅此处了解更多信息:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment
