1.按钮前后台事件
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" OnClientClick="alert(‘客房端验证，阻止向服务器端提交‘);return false;" />
2.注册相关事件：onblur,onclick,onchange
this.TextBox1.Attributes.Add("onchange", "alert(‘数据被改动，现检查输入是否符合规则‘);");
3.注册相关属性：
this.TextBox1.Attributes.Add("readOnly", "true");
4.引入JS文件
前台HTML页面：
1 <script type="text/javascript" src="JScript.js" language="javascript"></script>
2 <script type="text/javascript" language="javascript">
3 function fn_Name()
4 {
5 alert("JS");
6 }
7 </script>
后台cs页面：
this.RegisterClientScriptBlock("jsFile","<script type=‘text/javascript‘ src=‘JScript.js‘ language=‘javascript‘></script>");
5.点击按钮时 相关栏位 非空判断
1 function checkEmpty(txtObj,msgShow)
2 {
3 if(txtObj.value == "")
4 {
5 alert(msgShow);
6 return false;
7 }
8 }
9 <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" OnClientClick="return checkEmpty(TextBox1,‘TextBox1 不能为空‘)" />
6.通过ChcekBox的是否点选来控制其相对应的TextBox 是否可输入
1 function chkTextBox(chkObj,txtObj)
2 {
3 if(chkObj.checked==true)
4 {
5 txtObj.value = "";
6 txtObj.readOnly = false;
7 txtObj.focus();
8 }
9 if(chkObj.checked == false)
10 {
11 txtObj.value = "";
12 txtObj.readOnly = true;
13 }
14 }
15 <input id="Checkbox1" type="checkbox" onclick="chkTextBox(Checkbox1,TextBox1)" />
7.传值到模态窗口 并得到传回的值
1 var EnCodeQueryName = escape(Name);
2 var strPara = "‘dialogWidth: 400px;dialogHeight: 400px;dialogLeft: 300px;dialogTop: 200px;toolbar: no;menubar: no;resizable: yes;location: no;status: no;scrollbars= no‘";
3 var ReturnInfo = window.showModalDialog("QryName.aspx?&Name="+EnCodeQueryName +"&QueryID="+QueryType+"",‘‘,strPara);
4 if(ReturnInfo !=null)
5 {
6 var arrayReturnInfo = ReturnInfo .split("@");
7 document.all.drpID.value = arrayReturnInfo[1];
8 document.all.txtName.value= arrayReturnInfo[2];
9 }
8.弹出JS的确认对话框,并根据确认结果 触发后台相关操作
1 if(confirm(‘确认如何吗?‘))
2 {
3 document.all.hidbtn_Submit.click();
4 }
5 else
6 {
7 document.all.hidbtn_Cancel.click();
8 }
HTML页面相关代码：
1 <input id="hidbtn_Submit" type="button" value="确认修改" style="display:none;" onserverclick="hidbtn_Submit_ServerClick" runat="server" />
9.添加页面对快捷键的响应,如 按F2时 进行新增按钮的操作等
1 #region 添加页面对快捷键的响应
2 string strJS_ShortKey = "<script language=‘javascript‘ type=‘text/javascript‘ > ";
3 strJS_ShortKey += " document.onkeydown=shortKeyDown; ";
4 strJS_ShortKey += " function shortKeyDown() ";
5 strJS_ShortKey += " { ";
6 // 新增
7 if (this.ButtonCtl1.ImgBtn_AddFamily.Visible)
8 {
9 string btnInsertCID = this.ButtonCtl1.ImgBtn_Insert.ClientID.Trim();
10 //F2 - 113
11 strJS_ShortKey += " if(event.keyCode==‘113‘) ";
12 strJS_ShortKey += " { ";
13 strJS_ShortKey += " document.all(‘" + btnInsertCID + "‘).click();";
14 strJS_ShortKey += " event.keyCode= 0; ";
15 strJS_ShortKey += " event.returnValue = false; ";
16 strJS_ShortKey += " return false; ";
17 strJS_ShortKey += " } ";
18 }
19 // 修改
20 if (this.ButtonCtl1.ImgBtn_Edit.Visible)
21 {
22 string btnEditCID = this.ButtonCtl1.ImgBtn_Edit.ClientID.Trim();
23 //F3 - 114
24 strJS_ShortKey += " if(event.keyCode==‘114‘) ";
25 strJS_ShortKey += " { ";
26 strJS_ShortKey += " document.all(‘" + btnEditCID + "‘).click();";
27 strJS_ShortKey += " event.keyCode= 0; ";
28 strJS_ShortKey += " event.returnValue = false; ";
29 strJS_ShortKey += " return false; ";
30 strJS_ShortKey += " } ";
31 }
32 strJS_ShortKey += " } ";
33 //注册事件
34 Page.RegisterStartupScript("shortKey", strJS_ShortKey);
35 #endregion
10.弹出的提示 分行显示
1 alert(‘aaa \r\n bbb \r\n ccc‘);
如果是在后台.cs文件中注册
1 string strAlertContent = "aaa"+" \\r\\n "; 2 strAlertContent += "bbb" +" \\r\\n ";
11.点击GridView上的某一行时,行首列处的RadioButton处于选中状态,同时保存相关值在隐藏栏位
1 //用查询得的数据集进行绑定
2 if (dt.Rows.Count > 0)
3 {
4 //绑定
5 this.gv_InfoFromSendModule.DataSource = dt;
6 this.gv_InfoFromSendModule.DataBind();
7 //确定按钮显示
8 this.btn_OK.Visible = true;
9 this.txthid_RowCount.Text = dt.Rows.Count.ToString();
10 }
11 //GridView的RowDataBound
12 protected void gv_InfoFromSendModule_RowDataBound(object sender, GridViewRowEventArgs e)
13 {
14 if (e.Row.RowIndex < 0)
15 return;
16 e.Row.Attributes.Add("onclick", "radButton(‘" + e.Row.RowIndex.ToString() + "‘,‘" + e.Row.Cells[1].Text.Trim() + "‘);");
17 //RadioButton rad = (RadioButton)e.Row.Cells[0].FindControl("rad_Select");
18 //rad.Attributes.Add("onclick", "radButton(‘"+e.Row.RowIndex.ToString()+"‘,‘"+ e.Row.Cells[1].Text.Trim()+"‘);");
19 }
20 //行上所绑定的JS
21 function radButton(rowIndex,rowGUID)
22 {
23 //gv_InfoFromSendModule$ctl02$rad_Select
24 var rowCount = parseInt(document.all.txthid_RowCount.value)+2;
25 for(var i=2;i<rowCount;i++)
26 {
27 var tmpName;
28 if(i<10)
29 {
30 tmpName = "gv_InfoFromSendModule$ctl0"+i+"$rad_Select";
31 }
32 else
33 {
34 tmpName = "gv_InfoFromSendModule$ctl"+i+"$rad_Select";
35 }
36 //取得对应的Radio对象
37 var tmpRadio = document.getElementById(tmpName);
38 //当前选中 其他取消选中
39 if((i-2) == rowIndex)
40 {
41 tmpRadio.checked = true;
42 }
43 else
44 {
45 tmpRadio.checked = false;
46 }
47 }
48 document.all.txthid_GUID.value = rowGUID;
49 }
12.去掉前后空格
1 function fn_Trim(obj)
2 {
3 if(obj==null)
4 {
5 return;
6 }
7 else
8 {
9 var oldStr = obj.value;
10 var newStr = oldStr.replace(/^\s+|\s+$/g,"");
11 obj.value = newStr;
12 }
13 }
13.TextBox文本内容长度判断 看是否超过长度 超过返回true
1 function fn_IsTooLong(obj,varLength)
2 {
3 if(obj==null)
4 {
5 return false;
6 }
7 else
8 {
9 var valueStr = obj.value;
10 var len = valueStr.match(/[^ -~]/g) == null ? valueStr.length : valueStr.length + valueStr.match(/[^ -~]/g).length ;
11 if(len > parseInt(varLength) )
12 {
13 return true;
14 }
15 else
16 {
17 return false;
18 }
19 }
20 }
