我有一个典型的场景,其中有一个列表视图,然后是一个详细信息视图。您可以通过选择列表项进入详细信息视图。记录中的数据当然会通知布局视图的详细信息。我看到的是子模板的辅助函数被调用得太快(在列表视图呈现期间)以获取列表详细信息的数据。此外,当我单击列表中的项目时,它不会被调用。我究竟做错了什么?我将 Meteor 0.8.2 与 jQM 1.4.3 一起使用。
HTML 如下所示:
<!-- details page -->
<div data-role="page" data-theme="q" id="listdetail">
<div data-role="header" data-position="fixed">
<a data-rel="back" href="#" data-transition="slideleft" class="baack fa fa-arrow-left"></a>
<div id="detailTitle" class="headertitle"></div>
</div>
<!-- /header -->
<div data-role="content" class="ma-req-detail" id="details">
{{> qDetails}}
</div>
</div>
<!-- /details page -->
<template name="qList">
{{#each items}}
{{>qListItems}}
{{/each}}
</template>
<template name="qListItems">
<li>
<div id="msg-container-{{requestId}}" class="processing-msg">
<a href="#" data-rel="back" data-role="button" data-iconpos="notext" class="ui-btn-right msg-dismiss"><i class="fa fa-2x fa-times-circle"></i></a>
<p class="msg-text-{{requestId}}">Action pending...</p>
</div>
<a id="requestId" href="#listdetail" data-name="{{additionalProperties}}" data-transition="slide" class="{{#if isProcessing}}ui-disabled{{/if}}">
<p class="requestor">{{additionalProperties.requestedForUid}}</p>
<p class="description">week of {{additionalProperties.workWeekOf}}</p>
<p class="reqdate">total hours: </p>
</a>
</li>
</template>
<template name="qDetails" >
<div role="main" class="q-details">
<div data-role="navbar" class="week-nav">
<ul>
{{#each days}}
{{>navElements}}
{{/each}}
</ul>
</div>
</div>
<div class="ma-buttons ui-fieldcontain ui-footer-fixed">
<div data-role="controlgroup" data-type="horizontal" class="" data-position-fixed="true" data-position="bottom">
<a data-mini="true" href="#" id="approve-request"
class="ui-btn ui-btn-c ui-corner-r ui-icon-check ui-btn-icon-left ma-btn approve">Approve</a>
</div>
</div>
</template>
<template name="navElements">
<li><a id="{{day}}Nav" href="#{{day}}">{{day}}<br><span class="digital-date">{{date}}</span></a></li>
</template>
JS位是:
Template.qDetails.rendered = function() {
$('#details').trigger('create');
};
Template.qDetails.helpers({
days: function() {
//TODO need a way to delay this function to call when details template is shown
var dt = Session.get("record").additionalProperties.workWeekOf;
var days = [];
var weekday = new Array(7);
weekday[0] = "SAT";
weekday[1] = "SUN";
weekday[2] = "MON";
weekday[3] = "TUE";
weekday[4] = "WED";
weekday[5] = "THU";
weekday[6] = "FRI";
var dtVal = dt.getDate();
for (var i = 0; i < 7; i++) {
var dayObj = {};
dayObj.date = dtVal + i;
dayObj.day = weekday[i];
days.push(dayObj);
}
return days;
}
});
Template.qDetails.record = function () {
return Session.get("record");
};
在上面的代码中,当显示列表页面时调用“days”辅助函数,这会导致错误,因为它试图从尚未选择的记录中提取“workWeekOf”日期。选择记录后,如何才能进行此唯一呼叫?
