在选择中添加选项并在Internet Explorer上选择一个选项 [英] Adding options to a select and selecting one on internet explorer

问题描述

我有一个选择，我正在使用javascript填充选项。类似

I have a select, and I am filling the options using javascript. Something like

    var select = document.getElementById("selectBox");

    for (var i = 0; i < data.length; i++) {
        var option = document.createElement("option");
        option.innerHTML = data[i].name;
        option.value = data[i].id;
        select.appendChild(option);
    }

它适用于Firefox和Chrome，但不适用于Internet Explorer。当我检查IE上生成的html时，我看到

It works fine on Firefox and Chrome, but not on Internet Explorer. When I check the html generated on IE I see

    <select id="selectBox"/>

我可以做些什么让它在IE上工作吗？

Is there something I can do for it to work on IE?

编辑
刷新开发工具的html页面后（IE在html更改后没有这样做）我看到已经添加了选项，但是那里似乎是分配值的问题，我正在使用

EDIT After refreshing the html page on development tools(IE doesn't do this after the html change) I see that the options have been added, but there seems to be a problem assigning the value, I'm using

select.value = theValue;

推荐答案

问题在于我从中获取所选值。我正在使用ajax调用，IE（我认为）缓存了响应。当我改变一些值时，服务器必须给我正确的选择选项，但它给了我一个错误，因为IE总是在读相同的答案。

The problem was where I was getting the selected value from. I was using ajax calls, and IE was (I think) caching the response. When I changed some value, the server had to give me the correct select option, but it was giving me wrong one since IE was always reading the same answer.
