遵循本教程,
我已经为ASP.Net页面提供了3个asp内容占位符,他们已经在使用某种类型的脚本了,这不是问题。
问题是,我能够使用“OnClientClick”属性调用函数,但此函数在不同的.js文件中具有更多函数。如果我在调用其他函数之前发出警报它可以正常工作,但在它完成我的第一个功能之后就没有了。
教程列出了所有的javascript代码,这是我在ASP.Net内容中使用的代码,以使其工作,
<asp:Content ID="Content4" ContentPlaceHolderID="cphSubmit" runat="server">
<script type="text/javascript" src="/_layouts/1033/jquery.js"></script>
<script type="text/javascript" language="JavaScript" src="CustomDialog.js"></script>
<script type="text/javascript" language="JavaScript">
function ShowMessage()
{
alert("1");
SetText('Yes','No');
alert("2");
DisplayConfirmMessage('are you sure',180,90)
SetDefaultButton('btnConfOK');
return false;
}
</script>
<div id="divConfMessage" runat="server" style="BORDER-RIGHT:black thin solid; BORDER-TOP:black thin solid; DISPLAY:none; Z-INDEX:200; BORDER-LEFT:black thin solid; BORDER-BOTTOM:black thin solid">
<div style="BACKGROUND-COLOR: #6699cc;TEXT-ALIGN: center" id="confirmText">
</div>
<div style="Z-INDEX: 105;HEIGHT: 2%;BACKGROUND-COLOR: white;TEXT-ALIGN: center">
</div>
<div style="Z-INDEX: 105;BACKGROUND-COLOR: white;TEXT-ALIGN: center">
<asp:Button ID="btnConfOK" Runat="server" Text="OK"></asp:Button>
<asp:Button ID="btnConfCancel" Runat="server" Text="Cancel"></asp:Button>
</div>
</div>
<hr />
<asp:Button ID="btDelete" runat="server"
OnClientClick="ShowMessage();"
Text="Delete" UseSubmitBehavior="False" Width="200px" />
我暂时删除了其他一些控件,它显示警告“1”但未达到“2”,
这是 CustomDialog脚本,
var divWidth = '';
var divHeight = '';
var txtFirstButton = 'OK';
var txtSecondButton = 'Cancel'
function DisplayConfirmMessage(msg,width,height)
{
// Set default dialogbox width if null
if(width == null)
divWidth = 180
else
divWidth = width;
// Set default dialogBox height if null
if(height == null)
divHeight = 90
else
divHeight = height;
// Ge the dialogbox object
var divLayer = document.getElementById('divConfMessage');
// Set dialogbox height and width
SetHeightWidth(divLayer)
// Set dialogbox top and left
SetTopLeft(divLayer);
// Show the div layer
divLayer.style.display = 'block';
// Change the location and reset the width and height if window is resized
window.onresize = function() { if(divLayer.style.display == 'block'){ SetTopLeft(divLayer); SetHeightWidth(divLayer)}}
// Set the dialogbox display message
document.getElementById('confirmText').innerText = msg;
}
function SetTopLeft(divLayer)
{
// Get the dialogbox height
var divHeightPer = divLayer.style.height.split('px')[0];
// Set the top variable
var top = (parseInt(document.body.offsetHeight)/ 2) - (divHeightPer/2)
// Get the dialog box width
var divWidthPix = divLayer.style.width.split('px')[0];
// Get the left variable
var left = (parseInt(document.body.offsetWidth)/2) - (parseInt(divWidthPix)/2);
// set the dialogbox position to abosulute
divLayer.style.position = 'absolute';
// Set the div top to the height
divLayer.style.top = top
// Set the div Left to the height
divLayer.style.left = left;
}
function SetHeightWidth(divLayer)
{
// Set the dialogbox width
divLayer.style.width = divWidth + 'px';
// Set the dialogbox Height
divLayer.style.height = divHeight + 'px'
}
function SetText(txtButton1,txtButton2)
{
// Set display text for the two buttons
if(txtButton1 == null)
document.getElementById('btnConfOK').innerText = txtFirstButton;
else
document.getElementById('btnConfOK').innerText = txtButton1;
// Set display text for the two buttons
if(txtButton2 == null)
document.getElementById('btnConfCancel').innerText = txtSecondButton;
else
document.getElementById('btnConfCancel').innerText = txtButton2;
}
function SetDefaultButton(defaultButton)
{
// Set the focus on the Cancel button
document.getElementById(defaultButton).focus();
}
注意到它达到了这个功能
function SetText(txtButton1,txtButton2)
{
alert("2");
// Set display text for the two buttons
然后它迷路了,它试图从txtButton1获取值,这可能意味着,我的ASPX页面中的Div标签没有正确呈现:(
if(txtButton1 == null)
document.getElementById('btnConfOK').innerText = txtFirstButton;
else
document.getElementById('btnConfOK').innerText = txtButton1;
alert("3");
* *编辑 * 如果我删除了SetText函数,它会显示但是它不会触发我的“OnClick”方法并只刷新页面 ***
<asp:Button ID="Button1" runat="server" CausesValidation="False" CssClass="gradientbutton"
OnClick="btDelete_Click" OnClientClick="ShowMessage();this.disabled=true;this.value='Wait...';"
Text="Delete" UseSubmitBehavior="False" Width="200px" />
即使显示确认框
,也意识到在网页上出现错误表示findElementbyid(..)为null或不是对象
答案 0 :(得分:1)
我想这个
document.getElementById('btnConfOK')
应该使用ClientID而不是实际ID,因为它是.NET控件,ID将被重写。所以它应该是
document.getElementById('<%=btnConfOK.ClientID%>')
答案 1 :(得分:0)
也许有些人,为什么src被添加到网址没有'/'...
更改此行:
<script type="text/javascript" language="JavaScript" src="CustomDialog.js"></script>
要:
<script type="text/javascript" language="JavaScript" src="./CustomDialog.js"></script>
如果这对代码无效,或者您将其放在另一个位置0_0
