每次离开页面时,我希望清除之前的数据。我使用了.empty() 和 html('')方法来实现,但没有生效。请帮助我。
这里是我的代码 -
$("#leavebalstatus").html(" ");
$("#leavebalstatus").empty();
var leaveBallist= '';
for( i=0; i<getLeaveBal.length;i++){
leavebalgrp_name = getLeaveBal[i].find('Leave_Group_Name').text();
leavebal_code = getLeaveBal[i].find('Leave_Type_Code').text();
leavebal_name = getLeaveBal[i].find('Leave_Name').text();
leaveBallist += '<div data-role="collapsible" data-iconpos="right" data-collapsed-icon="carat-d" data-expanded-icon="carat-u" style="background:white;" id="leaveBalMainData"><h3 style="margin-bottom:2%;"><div style="width:100%;" id="leaveBal_contaner"><p style="display:inline-block;width:35%;background: red;text-align:center; color:white;">'+leavebal_name+'</p><p style="display:inline-block;width:60%; margin-left:5%;">'+leavebalgrp_name+'</p></div></h3>';
for(k=0; k<collapseArray.length;k++){
if (i == k){
leaveBallist += '<p style="width:100%;margin-left:5%;"><span style="width:33%; dispaly:inlne-block;float:left;">Entitled</span><span style="width:33%; dispaly:inlne-block;float:left;">Availed</span><span style="width:33%; dispaly:inlne-block;float:left;">Balance</span></p><p style="width:100%;margin-left:5%;"><span style="width:33%; dispaly:inlne-block; float:left;">'+collapseArray[i].find('LeaveEntitled').text()+'</span><span style="width:33%; dispaly:inlne-block; float:left;">'+collapseArray[i].find('LeaveAvailed').text()+'</span><span style="width:33%; dispaly:inlne-block; float:left;">'+collapseArray[i].find('LeaveBal').text()+'</span></p>';
}
}
leaveBallist += '<p style="width:100%;"><hr style="width:100%;"></p><p style="width:100%;"><span style="color:red; width:100%;font-size:16px;margin-left:42%" onclick="applyLeaveForBal('+i+');">APPLY</span></p></div>';
}
$('#leavebalstatus').html(leaveBallist);
// $('#leavebalstatus').collapsible();
$('#leavebalstatus').collapsibleset( "refresh" );
$('#leavebalstatus').trigger("create");
清除页面数据时,我尝试调用了以下代码:
$(document).on("pagehide", "#leavebal_page", function(event, ui){
alert(event.target);
$('#leavebalstatus').empty();
$('#leavebalstatus').html('');
});
但两者都不能工作。谢谢帮助。
.empty()
和.html("")
中的一个;因为.html()
的第一件事就是调用.empty()
。 - Pointypagehide
事件已被弃用。如果你使用的是> 1.4.0
,请使用pagecontainerhide
代替pagehide
。请参阅文档http://api.jquerymobile.com/pagehide。 - Harish Kommuri
