即不支持'包括'方法 [英] ie does not support 'includes' method

问题描述

我一直在研究一个项目并开发一个JavaScript框架。原始代码约700行，所以我只粘贴了这一行。 include方法在Internet Explorer上不起作用。对此有什么解决方案吗？

I have been working on a project and developing a JavaScript framework. The original code is about 700 lines so I only pasted this line. The includes method doesn't work on Internet Explorer. Is there any solution for this?

var row_cells = tbl_row.match(/<td[\s\S]*?<\/td>/g);

    row.Cells = new Array();
    if (onRowBindFuncText != null) { /*Fonksyon tanımlanmaışsa daha hızlı çalış*/

        var cellCount = 0;
        for (i = 0; i < row_cells.length; i++) {

            var cell = new Cell();
            $.each(this, function (k, v) {

                if ((row_cells[i]+"").includes("#Eval(" + k + ")")) {

                    cell.Keys.push(new Key(k,v));

推荐答案

因为它在IE中不受支持，所以在Opera中也不支持（查看兼容性表），但您可以使用建议的 polyfill ：

Because it's not supported in IE, it is not supported also in Opera (see the compatibility table), but you can use the suggested polyfill:

Polyfill

此方法已被添加到ECMAScript 2015规范中，可能尚未在所有JavaScript实现中提供。但是，您可以轻松地填充此方法：

This method has been added to the ECMAScript 2015 specification and may not be available in all JavaScript implementations yet. However, you can easily polyfill this method:

if (!String.prototype.includes) {
  String.prototype.includes = function(search, start) {
    'use strict';
    if (typeof start !== 'number') {
      start = 0;
    }

    if (start + search.length > this.length) {
      return false;
    } else {
      return this.indexOf(search, start) !== -1;
    }
  };
}
