you can bind click event via jQuery, like this
你可以通过jQuery绑定点击事件，就像这样
$("#id_of_your_imagebutton").click(function(){
//your code for event here
});
If you use asp.net 4, you can set ClientIDMode="Static" to your ImageButton and get "send" for ID, or you can get ID via FireBug if you use earler versions
如果您使用 asp.net 4，您可以将 ClientIDMode="Static" 设置为您的 ImageButton 并为 ID 获取“发送”，或者如果您使用早期版本，则可以通过 FireBug 获取 ID

you can try like this, in code behind file.
你可以像这样尝试，在代码隐藏文件中。
Protected void Page_Load(object sender, EventArgs e)
{
send.Attributes.Add("onclick", "javascript:preview(); return false;" ) // retruning false will avoid postback
}
