在javascript函数里调用_doPostBack( 'LinkButton1 ', ' ')，不能触发cs文件里的相应函数？
aspx:
<script language= "javascript ">
function Getsort(obj)
{
document.all.sortfield.value=obj;
if(document.all.sortstring.value== 'ASC ')
document.all.sortstring.value= 'DESC ';
else if(document.all.sortstring.value== 'DESC ')
document.all.sortstring.value= 'ASC ';
_doPostBack( 'LinkButton1 ', ' ');
}
</script>
cs:
private void LinkButton1_Click(Object Sender, System.EventArgs e)
{
string sortstring=Request.Form[ "sortstring "].ToString();
string sortfield=Request.Form[ "sortfield "].ToString();
string fullsortstring=sortstring+ " "+sortfield;
if(fullsortstring!= " "&&fullsortstring!=null)
BindDataSource(fullsortstring);
}
------解决方案--------------------------------------------------------
在CS里重新注册一下JS
Ajax.Utility.RegisterTypeForAjax(typeof(_doPostBack));
------解决方案--------------------------------------------------------
_doPostBack( 'LinkButton1 ', ' ');
第二个参数应该是你CS文件中的LinkButton1_Click事件
_doPostBack( 'LinkButton1 ', 'LinkButton1_Click ');
------解决方案--------------------------------------------------------
_doPostBack
前面是两个下划线
__doPostBack
------解决方案--------------------------------------------------------
双击事件？
LinkButton1只能执行单击事件啊
------解决方案--------------------------------------------------------
zwwlovezy1()
_doPostBack( 'LinkButton1 ', ' ');
第二个参数应该是你CS文件中的LinkButton1_Click事件
_doPostBack( 'LinkButton1 ', 'LinkButton1_Click ');
以上为正解！！！lz请注意！
------解决方案--------------------------------------------------------
_doPostBack
前面是两个下划线
__doPostBack
------解决方案--------------------------------------------------------
哦，刚回复错了，正解是_doPostBack前面是两个下划线：__doPostBack，而其第二个参数你可以用来传递到后台的，例如：
js：
var value = "add ";
__doPostBack( "btn1 ",value);
cs:
private void btn1_Click(object sender, System.EventArgs e)
{
string opt = Request.Form[ "__EVENTARGUMENT "];
if(opt== "add ")
{
//do something yourself here
}
}
------解决方案--------------------------------------------------------
对
但你 HTML里写的是双击事件 不知道放个linkbutton行不行
------解决方案--------------------------------------------------------
<script language= "javascript ">
function Getsort(obj)
{
document.all.sortfield.value=obj;
if(document.all.sortstring.value== 'ASC ')
document.all.sortstring.value= 'DESC ';
else if(document.all.sortstring.value== 'DESC ')
document.all.sortstring.value= 'ASC ';
<%=Page.GetPostBackClientEvent(this. 'LinkButton1 ', " ")%>
}
</script>
这样由服务器自动产生__doPostBack方法
------解决方案--------------------------------------------------------
(1.) <asp:LinkButton ID= "LinkButton1 " Runat=server> </asp:LinkButton>
