jQTouch 动态网络应用程序?
我正在开发一个动态变化的网络应用程序。我使用 javascript 和 jQuery 用
和
填充 DIV。例如,我从使用 JavaScript 动态构建的一个菜单开始。从该菜单中,根据所选项目,将调用另一个 javascript 函数来动态填充相应的 DIV。当我不断动态构建子菜单并且 JQTouch 不切换到下一页时,问题就出现了。在以下代码中,alert('what')
显示在 iPhone 上,但从未切换到 ePresentationDetails DIV。我尝试用 jQT.goTo(); 强制它但这通常会导致更多问题,并且不能解决问题。
基本 html 代码:
<div id="home">
<div class="toolbar">
<a class="blueButton" href="javascript: void(0);" onClick="$('#logout').show();">Logout</a>
<h1>AllaccessMD</h1>
</div>
<div id="logout" style="display:none;">
<div id="confirmBox">
Are you sure?
<a class="logoutButton" href="javascript: void(0);" onClick="logOut();">Logout</a>
<a class="cancelButton" href="javascript: void(0);" onClick="$('#logout').hide();">Cancel</a>
</div>
</div>
<h1>Home</h1>
<ul class="edgetoedge" id="ulHome"></ul>
</div>
<div id="ePresentations">
<div class="toolbar">
<a class="button back" href="#">Back</a>
<h1>AllaccessMD</h1>
</div>
<div id="ePresentationsData"><div class="progress"><font style="padding-right:5px;">Loading...</font><img border="0" src="Images/ajax-loader.gif" /></div>
</div>
</div>
<div id="ePresentationDetails">
<div class="toolbar">
<a class="button back" href="#">Back</a>
<h1>AllaccessMD</h1>
</div>
<div id="ePresentationDetailsData"><div class="progress"><font style="padding-right:5px;">Loading...</font><img border="0" src="Images/ajax-loader.gif" /></div>
</div>
</div>

$('#ePresentationDetailsData').html(html);
}
}
xmlhttp.open("GET","Lib/ePresentations.cfm?Type=getEP&id=" + id,true);
xmlhttp.send();*/
$('#ePresentationDetailsData').html('I dont get called?');
}
我做错了什么?也许有更好的方法来做到这一点?
谢谢!!
I'm working on a dynamically changing web app. I'm using javascript and jQuery to populate DIV's with <li>
's and <a>
's. For example, I start with one menu dynamically built with javascript. From that menu, depending on item selected, another javascript function gets called to dynamically populate the corresponding DIV. The problem coming when I keep dynamically building submenu's and JQTouch doesn't switch to the next page.
In the following code, the alert('what')
displays on an iPhone but never switches to the ePresentationDetails DIV. I have tried forcing it with jQT.goTo(); but that usually causes more issues and doesn't fix the problem.
Basic html code:
<div id="home">
<div class="toolbar">
<a class="blueButton" href="javascript: void(0);" onClick="$('#logout').show();">Logout</a>
<h1>AllaccessMD</h1>
</div>
<div id="logout" style="display:none;">
<div id="confirmBox">
Are you sure?
<a class="logoutButton" href="javascript: void(0);" onClick="logOut();">Logout</a>
<a class="cancelButton" href="javascript: void(0);" onClick="$('#logout').hide();">Cancel</a>
</div>
</div>
<h1>Home</h1>
<ul class="edgetoedge" id="ulHome"></ul>
</div>
<div id="ePresentations">
<div class="toolbar">
<a class="button back" href="#">Back</a>
<h1>AllaccessMD</h1>
</div>
<div id="ePresentationsData"><div class="progress"><font style="padding-right:5px;">Loading...</font><img border="0" src="Images/ajax-loader.gif" /></div>
</div>
</div>
<div id="ePresentationDetails">
<div class="toolbar">
<a class="button back" href="#">Back</a>
<h1>AllaccessMD</h1>
</div>
<div id="ePresentationDetailsData"><div class="progress"><font style="padding-right:5px;">Loading...</font><img border="0" src="Images/ajax-loader.gif" /></div>
</div>
</div>
Javascript file:
function setupHome(){
if(localStorage.role == "Specialist"){
var homeUL = '<li class="arrow"><a id="aEP" rel="s,' + localStorage.userID + '" href="#ePresentations">My E-Presentation</a></li>'
+ '<li class="arrow"><a id="aN" rel="s,' + localStorage.userID + '" href="#date">My Newsletter</a></li>'

+ '<li class="arrow"><a id="aMP" rel="s,' + localStorage.userID + '" href="#date">Medical Partners</a></li>'
+ '<li class="arrow"><a id="aS" rel="s,' + localStorage.userID + '" href="#date">Search</a></li>'
+ '<li class="arrow"><a id="aP" rel="s,' + localStorage.userID + '" href="#date">Profile</a></li>';
$('#ulHome').html(homeUL);

+ '<li class="arrow"><a id="aP" rel="m,' + localStorage.userID + '" href="#date">Profile</a></li>';
$('#ulHome').html(homeUL);
}
$('#ePresentations').bind('pageAnimationStart', function (e){setupEPresentations(getID($('#aEP').attr('rel')).id);});
}
function setupEPresentations(sID){
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState==4 && xmlhttp.status==200) {
var epObject = JSON.parse(xmlhttp.responseText);
var html = '<h1>Dr. ' + epObject.DR.DATA[0][1] + ' E-Presentation\'s</h1>';
if(epObject.EP.DATA.length == 0){
html += '<div><p>There are currently no E-Presentation\'s for this doctor.</p></div>';
} else {
html += '<ul class="edgetoedge">';
for(var i in epObject.EP.DATA){
html += '<li class="arrow"><a id="' + epObject.EP.DATA[i][0] + '" href="#ePresentationDetails">' + epObject.EP.DATA[i][1] + '</a></li>';
}
html += '</ul>';
}
$('#ePresentationsData').html(html);
$('#ePresentationsData li a').click(function(e) {alert('what');setupEPresentationDetails(this.id);});
}
}
xmlhttp.open("GET","Lib/ePresentations.cfm?Type=getAllEPsID&sID=" + sID,true);
xmlhttp.send();
}
function setupEPresentationDetails(id){
/*xmlhttp.onreadystatechange = function() {

var epObject = JSON.parse(xmlhttp.responseText);
var html = '<h1>Dr. ' + epObject.DATA[0][0] + ' E-Presentation</h1>';
html += '<p>';
//html += '<br />' + epObject.DATA[0][2].format("mmmm dd, yyyy");
html += '<br /><strong>Rating:</strong> ' + Math.ceil(epObject.DATA[0][4]) + ' / 5 (' + epObject.DATA[0][5] + ' votes cast)';
html += '<br /><br /><a rel="external" href="http://www.youtube.com/v/' + epObject.DATA[0][3] + '">Click here to view E-Presentation</a>';
html += '</p>';
$('#ePresentationDetailsData').html(html);
}
}
xmlhttp.open("GET","Lib/ePresentations.cfm?Type=getEP&id=" + id,true);
xmlhttp.send();*/
$('#ePresentationDetailsData').html('I dont get called?');
}
What am I doing wrong? Maybe there is a better way to do this?
Thanks!!

您使用什么版本的 JQT?
您是否将整个应用程序包装在
中?
您是否使用 Safari 开发者模式查看过列表 HREF 在呈现时实际是什么?
我会查看渲染的 HREF 中的以下内容:
确保 html 是它应该的样子。 rel= 或你的引号没有被转义可能会导致它失败。但我没有看到任何明显的事情表明你做错了。
您是否有可以发送给我的链接,以便我可以实际调试它?
What version of JQT are you using?
Are you wrapping your entire app in the
<div id="jqt"></div>
?Have you looked at it using Safari developer mode to see what the list HREFs actually are when they are rendered?
I would look at the rendered HREF for these:
Make sure the html is what it should be. The rel= or your quotes not being escaped might be throwing it off. But I don't see anything obvious that you are doing wrong.
Do you have a link you can send me so I can debug it in action?
