Internet Explorer 11 JavaScript Let语句 [英] Internet Explorer 11 JavaScript Let Statement

问题描述

我有相当复杂的代码，该代码通过"for"循环依次执行多个AJAX调用.该代码之所以有效，是因为在将范围分配给循环索引时使用了"Let"语句. (让i = 0； i< 2； i ++){}.

I have rather complex code that is executing a multiple AJAX call in sequence through the 'for' loop. This code works because I use 'Let' statement when assigning scope to a loop index. (let i = 0; i < 2; i++) { }.

但是，让"给了我期望的"； Internet Explorer 11中的错误，虽然代码在其他浏览器中可以正常工作，但我尝试将"let"移出循环，但仍然失败，无论在何处使用该语句，无论循环如何，它似乎都失败了，请让我知道这是什么解决方法，因为IE 11应该与'Let'语句兼容.

However, 'Let' is giving me " Expected ';' error in Internet Explorer 11, While the code is working perfectly in other browsers. I have tried to move "let" out of the loop but it still fails, it seem to fail wherever the statement is used regardless of the loop. Please let me know what is the workaround for this as IE 11 is supposed to be compatible with 'Let' statement.
