我在android phonegap中创建了应用程序。在我的应用程序中,我在div中添加了动态加载的列表。如何使用iscroll为动态div添加滚动条。我想使用iscroll.how为动态div添加滚动条来执行此操作 我的代码是
HTML:
<div class="sidemenu" ></div>
</div>
风格:
#scroller
{
top:90px;
position:absolute; z-index:1;
width:90%;
height:40px;
background-color:#FFFFFF;
}
li
{
list-style:none;
}
脚本:
iscroll:
var myScroll;
function loaded() {
myScroll = new iScroll('scroller', {
useTransform: false,
vScroll: true,
onBeforeScrollStart: function (e) {
var target = e.target;
while (target.nodeType != 1) target = target.parentNode;
if (target.tagName != 'SELECT' && target.tagName != 'INPUT' && target.tagName != 'TEXTAREA')
e.preventDefault();
}
});
}
document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false);
document.addEventListener('DOMContentLoaded', setTimeout(function () { loaded(); }, 0), false);
/** scrollbar for dynamic div*/
function doIscrollRefresh () {
setTimeout(function () {
myScroll.refresh();
}, 0);
}
动态div: 我已从localdatabase中重新获取值并动态附加到div
function list1(alphabet)
{
doIscrollRefresh ();
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady()
{
var db = window.openDatabase("createdb", "1.0", "PhoneGap Demo", 200000);
db.transaction(queryDB, errorCB,successCB);
}
function queryDB(tx)
{
var a=alphabet;
tx.executeSql("SELECT Textvalue FROM TextValue WHERE Textvalue LIKE '" + a + "%'",[], querySuccess, errorCB);
}
function querySuccess(tx,results)
{
$(".sidemenu").append("<li>"+"<label style='background-color:#C1CDD9' >"+alphabet+ "</label>"+"</li>");
for (i = 0; i < results.rows.length; i++)
{
$(".sidemenu").append("<li>"+"<a id='"+i+"' href='#'>" +results.rows.item(i).Textvalue + "</a>"+ "<hr/>"+ "</li>");
}
$(".sidemenu").append("<hr/>");
}
function errorCB(err)
{
alert("Error processing SQL: "+err.code);
}
function successCB()
{
//alert("appended");
}
}
它显示了logcat中的错误。错误是myScroll未定义不是对象。 请告诉我解决方案。如何添加动态div.please的滚动条指导me.thanks提前

嗨,我不是什么意思,但如果iscroll说你的iscroll没有定义它,因为你调用loaded();在开始时起作用,然后在你的动态代码后面实例化,所以iscroll无法找到你的元素!
我建议你在动态div显示并回滚
之后回调加载的函数只需回忆一下loaded();函数或使用iScroll.refresh();当你的元素已经显示时起作用。
function querySuccess(tx,results)
{
$(".sidemenu").append("<li>"+"<label style='background-color:#C1CDD9' >"+alphabet+ "</label>"+"</li>");
for (i = 0; i < results.rows.length; i++)
{
$(".sidemenu").append("<li>"+"<a id='"+i+"' href='#'>" +results.rows.item(i).Textvalue + "</a>"+ "<hr/>"+ "</li>");
}
$(".sidemenu").append("<hr/>");
********************************************************************
loaded();
/* or you can use*/
myScroll.refresh();
*********************************************************************
}
提醒的重要一点是在显示内容并具有样式后调用或刷新iscroll
祝你好运!
