Javascript调用C#里的函数
<input   id= "fleRead "   type= "file "     runat= "server "     onreadystatechange= "btnReadImg_Click(); "   onpropertychange= "document.all._ctl0_ContentPlaceHolder_Condition_imgPhoto.src= 'file:/// '+this.value;   document.all._ctl0_ContentPlaceHolder_Condition_hidUrl.value=this.value; "   enableviewstate=true/>
<asp:button   id= "btnReadImg "     tabIndex= "-1 "   runat= "server "   CssClass= "CommonButton "   Text= "取込 "> </asp:button>
C#里
  protected   void   btnReadImg_Click()
                {
                }
怎么调用btnReadImg_Click()?

利用_dopostback,

------解决方案--------------------
用页面回传机质
也就是楼上说的_dopostback()，去网上查查查关资料
------解决方案--------------------
<script>
function func()
{
document.getElementById( 'btnReadImg ').click();
}
</script>
------解决方案--------------------
1.拖一个linkbutton到页面
2.双击产生后台事件linkButton_Click(...)
3.隐藏按钮:linkbutton.Style.Add( "display ", "none ");
4.前台调用, onclick= "javascript:__doPostBack( 'linkButton ', ' ') "


够清楚不?
