警报。如何获得news_id在项目点击提醒
这是我的HTML页面:
<body>
<div data-role="page" id="taxmanhomepage" data-theme="e">
<div data-role="header" data-position="fixed" data-tap-toggle="false" data-theme="e">
<h4 align="center">Taxmann Demo App</h4>
</div>
<div data-role="content" data-theme="e">
<a data-role="button" onclick="callservice()">Webservice</a>
Todays Headlines:
<div class="content-primary">
<ul id="newlist" data-role="listview" data-inset="true"data-filter-theme="e" data-divider-theme="e">
</ul>
</div>
</div>
</div>
</body>
这是我的JavaScript代码:
var URL="http://www.taxmann.com/TaxmannWhatsnewService/mobileservice.aspx?service=corporatelaws";
var news_id=null;
var news_title=null;
var news_short_description=null;
var new_hash = {};
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {}
function backToHome() {
$.mobile.changePage('#taxmanhomepage', {
reverse : false,
changeHash : false
});
}
$(document).on('pagebeforeshow','#newslistpage',function(event){
$('#newlist').empty();
});
function callservice(){
$.ajax({
type : "GET",
url : URL,
dataType : "json",
cache : false,
error : function(xhr, ajaxOptions, thrownError) {
debugger;
},
success : function(response, status, xhr) {
response=xhr.responseText;
var responseArray = JSON.parse(response);
console.log(responseArray);
var length = responseArray.length;
var html='';
for(i=0;i<length;i++) {
news_id=$.trim(responseArray[i].news_id);
news_title=$.trim(responseArray[i].news_title);
news_short_description=$.trim(responseArray[i].news_short_description);
new_hash[news_id]=[news_title,news_short_description];
$("#newlist").append("<li 'style='font-size:10pt';'font-weight:bold';' ><a href='#' ><h1 class='myHeader'>"+news_title+"</h1><br><h6 class='myHeader'>"+news_short_description+"</h6></a></li>");
}
$("#newlist").append("</ul>");
$('#newlist').listview('refresh');
$('#newlist').children('li').on('click', function(){
var index = $(this).index();
//var text = $(this).text();
alert(index);
});
}
});
}
改变你的代码是这样的追加部分,
$("#newlist").append($("<li/>").data("newsId", news_id).html("<a href='#' ><h1 class='myHeader'>" + news_title + "</h1><br/><h6 class='myHeader'>" + news_short_description + "</h6></a>"));
并改变这样的单击事件,
$('#newlist').on('click', 'li',function() {
var index = $(this).index();
//var text = $(this).text();
alert($(this).data("newsId"));
});
把news_id
为li
项目的data-attribute
,然后检索:
$("#newlist").append("<li data-news-id='" + news_id + "' rest of string");
$('#newlist').children('li').on('click', function(){
var news_id = $(this).attr('data-news-id');
alert(news_id);
});
如果您不希望该属性可见,那么使用data()
:
$("<li rest of string").data('news_id', news_id).appendTo($('#newlist'));
$('#newlist').children('li').on('click', function(){
var news_id = $(this).data('news_id');
alert(news_id);
});
我不想在ListView上显示News_id我只能显示news_title和news_showrt Descriton – user2372154 2013-05-13 08:58:25
