Question

我想使用jquery比较一些文本，例如

 var text = "ctl00_ContentPlaceHolder1_txtActivity";
 var activityId = text.includes("txtActivity");

或

 var activityId = (isd.indexOf("txtActivity") > -1);

上面的代码在crome和firefox中成功运行但它在IE中出错有没有其他方法来解决它请帮忙

Answer 1

使用模式匹配来执行此操作：

<div class="form-group">
  <form>
    <input type="text" ng-model="description" name="description" class="form-control" required>
    <input type="text" ng-model="description" name="description" class="form-control" required>
    <input type="text" ng-model="description" name="description" class="form-control" required>
    <button type="submit">Save</button>
  </form>
</div>

indexOf功能适用于所有浏览器。只需删除inculdes路径，然后将变量名称更改为text：

＆＃13;

var text = "ctl00_ContentPlaceHolder1_txtActivity";
var activityId = text.indexOf("txtActivity") > -1;

console.log(activityId);

＆＃13;

尝试此代码.. indexof工作所有浏览器..

<script>
var text = "ctl00_ContentPlaceHolder1_txtActivity";

var n = text.indexOf("txtActivityda");
if(n!== -1)
{
console.log("found")
}
 else
{
console.log("not found")
}
</script>
