826天前if(!Page.IsPostBack) |
{ |
System.Text.StringBuilder s = new System.Text.StringBuilder(); |
s.Append("a();"); |
s.Append(this.GetPostBackEventReference(this.Button1)); |
this.Button1.Attributes.Add("onclick",s.ToString()); |
} |
a() 是 JS |
function a() |
{ |
var ok=document.getElementById('Button1'); |
ok.disabled = true; |
return true; |
} |
btnSave.Attributes.Add("onclick","this.disabled='true';"+GetPostBackEventReference(btnSave)); |
|
一个问题稍微困扰了一下，后来解决了，btnSave.Attributes.Add("onclick","a();"+GetPostBackEventReference(btnSave)); 如果a()这个函数还包含其他验证，比如说一些正则验证等，btnSave.Attributes.Add("onclick","return a();"+GetPostBackEventReference(btnSave)); 则不能进行。可以将JS代码全部在CS文件中写就OK拉。 |
this.btnSubmit.Attributes["onclick"]=this.GetPostBackEventReference(this.btnSubmit)+";this.disabled=true;";//防止重复提交 |
System.Text.StringBuilder s = new System.Text.StringBuilder(); s.Append("var ok=document.getElementById('Button1'); "); |
s.Append("ok.disabled = true; "); |
s.Append(this.GetPostBackEventReference(this.Button1)); |
this.Button1.Attributes.Add("onclick",s.ToString()); |
//.net 2.0以上 |
Button1.Attributes.Add("onclick", "this.disabled=true;" + this.ClientScript.GetPostBackEventReference(Button1, "")); |
<asp:Button ID="btnSumbit" runat="server" UseSubmitBehavior="false" OnClientClick="this.value='Sumbit';this.disabled=true; " Text="Sumbit" OnClick="btnSumbit_Click" /> |
protected void Page_Load(object sender, EventArgs e) |
{ |
btn.Attributes.Add("onclick", "state=true;"); |
StringBuilder sb = new StringBuilder(); |
sb.Append("if (!state) return;"); |
sb.Append("var button=document.getElementByIdx_x('btn');"); |
sb.Append("button.value='Please Wait...';"); |
sb.Append("document.body.style.cursor='wait';"); |
sb.Append("button.disabled=true;"); |
string strScript = "<script>"; |
strScript = strScript + "var state=false;"; |
//将函数绑定到页面的onbeforeunload事件: |
strScript = strScript + "window.attachEvent('onbeforeunload',function(){" + sb.ToString() + "});"; |
strScript = strScript + "</" + "script>"; |
Page.RegisterStartupScript("onbeforeunload", strScript); |
} |
protected void Submit_Click(object sender, EventArgs e) |
{ |
//模拟长时间的按钮处理 |
System.Threading.Thread.Sleep(2000); |
Response.Write("<script>alert('bbbbbb!!');" + "</" + "script>"); |
} |
<asp:Button ID="btn" Text="Submit" OnClick="Submit_Click" |
