Javascript调用C#里的函数
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()?
[解决办法]
利用_dopostback,

[解决办法]
用页面回传机质
也就是楼上说的_dopostback()，去网上查查查关资料
[解决办法]
<script>
function func()
{
document.getElementById( 'btnReadImg ').click();
}
</script>
[解决办法]
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?
