我有一段代码，它适用于除Internet Explorer和Opera之外的所有浏览器。
以下是代码：JSFiddle
(async () => {在IE中指向行 protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
BindCS();
BindCC();
BindAG();
List<LUT_Assets_Masters> dt = this.GetData();
rptMarkers.DataSource = dt;
rptMarkers.DataBind();
}
}
private List<LUT_Assets_Masters> GetData()
{
AssetTaggingEntities context = new AssetTaggingEntities();
List<LUT_Assets_Masters> am1 = null;
if (DDSearch.SelectedValue == "1" && DDStatus.SelectedIndex >= 0 && DDCondition.SelectedIndex >= 0 && DDGroup.SelectedIndex >= 0)
{
am1 = (from am in context.LUT_Assets_Masters
where am.CSID == DDStatus.SelectedIndex
&& am.CCID == DDCondition.SelectedIndex
&& am.AGrpID == DDGroup.SelectedIndex
select am).ToList();
}
else
{
am1 = (from am in context.LUT_Assets_Masters select am).ToList();
}
return am1;
}
protected void DDS_SelectedIndexChanged(object sender, EventArgs e)
{
List<LUT_Assets_Masters> dt = this.GetData();
rptMarkers.DataSource = dt;
rptMarkers.DataBind();
}
protected void DDGroup_SelectedIndexChanged(object sender, EventArgs e)
{
List<LUT_Assets_Masters> dt = this.GetData();
rptMarkers.DataSource = dt;
rptMarkers.DataBind();
}
protected void DDCondition_SelectedIndexChanged(object sender, EventArgs e)
{
List<LUT_Assets_Masters> dt = this.GetData();
rptMarkers.DataSource = dt;
rptMarkers.DataBind();
}
protected void DDStatus_SelectedIndexChanged(object sender, EventArgs e)
{
List<LUT_Assets_Masters> dt = this.GetData();
rptMarkers.DataSource = dt;
rptMarkers.DataBind();
}
protected void DDSearch_SelectedIndexChanged(object sender, EventArgs e)
{
if (DDSearch.SelectedValue == "1")
{
Search.Visible = true;
BArea.Visible = false;
}
if (DDSearch.SelectedValue == "2")
{
Search.Visible = false;
BArea.Visible = true;
}
}
知道为什么会这样，以及如何解决它？
正如我注意到它是一个ES6代码，无论如何转换一个与旧浏览器友好的不同代码仍然提供相同的输出？
答案 0 :(得分：0)
async和await，自版本42以来仅支持Opera（请参阅bottom of MDN article）。不要在旧浏览器中使用ES6 - 使用Babel或其他转换器转换到ES5（尽管在IE的情况下可能是ES3？）。
