我正在尝试简化我的代码,但遇到的问题是当它放在每个循环中时它不起作用。
以下是我要做的事情: - html有 n 父DIV,它通过AJAX调用生成报告来提取数据 - 报告中的每个div使用数据属性来定义要提取的报告 - 基于报告的结果,它应该用相应的结果填充html。
HTML代码(简化,使用n = 2):
<div class="widget-box widget-hits card no-border bg-white no-margin" data-widget-report="widget-hits">
<div class="container-xs-height full-height">
<div class="row-xs-height">
<div class="col-xs-height col-top">
<div class="card-header top-left top-right">
<div class="card-title text-black hint-text">
<span class="font-montserrat fs-11 all-caps">Weekly Hits
<i class="far fa-chevron-right p-l-5"></i>
</span>
</div>
<div class="card-controls">
<ul>
<li>
<a data-toggle="refresh" class="card-refresh text-black" href="#">
<i class="far fa-circle fa-xs"></i>
</a>
</li>
</ul>
</div>
</div>
</div>
</div>
<div class="row-xs-height ">
<div class="col-xs-height col-top relative">
<div class="row">
<div class="col-sm-6">
<div class="p-l-20 widget-total">
<h3 class="no-margin p-b-5"></h3>
<p class="small hint-text m-t-5">
<span class="label m-r-5">%</span>
</p>
</div>
</div>
<div class="col-sm-6">
</div>
</div>
<div class="widget-chart"></div>
</div>
</div>
</div>
</div>
<div class="widget-box widget-sales card no-border bg-white no-margin" data-widget-report="widget-sales">
<div class="container-xs-height full-height">
<div class="row-xs-height">
<div class="col-xs-height col-top">
<div class="card-header top-left top-right">
<div class="card-title text-black hint-text">
<span class="font-montserrat fs-11 all-caps">Weekly Sales
<i class="far fa-chevron-right p-l-5"></i>
</span>
</div>
<div class="card-controls">
<ul>
<li>
<a data-toggle="refresh" class="card-refresh text-black" href="#">
<i class="far fa-circle fa-xs"></i>
</a>
</li>
</ul>
</div>
</div>
</div>
</div>
<div class="row-xs-height ">
<div class="col-xs-height col-top relative">
<div class="row">
<div class="col-sm-6">
<div class="p-l-20 widget-total">
<h3 class="no-margin p-b-5"></h3>
<p class="small hint-text m-t-5">
<span class="label m-r-5">%</span>
</p>
</div>
</div>
<div class="col-sm-6">
</div>
</div>
<div class="widget-chart"></div>
</div>
</div>
</div>
</div>
JS:
$('.widget-box').each(function() {
$widget_report = $(this).data('widget-report');
if ($widget_report !== undefined) {
$.ajax({
type: 'get',
url: '/admin/reports/' + $widget_report,
dataType: 'json',
success:
function(data) {
if (data.success) {
var labelsData = [];
var seriesData = [];
var trend = data.trend * 100;
widget_class = '.' + $widget_report + ' .widget-chart';
console.log(widget_class);
$(this).find('.widget-total h3').text(data.total);
$(this).find('.widget-total p span').text(trend + '%');
trend_span = $(this).find('.widget-total p').children('span');
if(data.trend > 0) {
$(this).find('.widget-total p span.label').addClass('label-success');
$(this).find('.widget-total p').text('Higher');
}
else {
$(this).find('.widget-total p span.label').addClass('label-important');
$(this).find('.widget-total p').text('Lower');
}
$(this).find('.widget-total p').prepend(trend_span);
$.each(data.values, function(key, value){
date = new Date(value.label + 'T00:00:00');
labelsData.push(date.getMonth() + 1 + '/' + date.getDate());
seriesData.push(value.value);
});
chartData = {
labels: labelsData,
series: [seriesData]
}
alert(widget_class);
new Chartist.Bar(widget_class, chartData, {
axisX: {
showGrid: false
},
axisY: {
showGrid: false,
showLabel: false
}
});
}
}
});
}
});
以下是我遇到的问题:
我在这个问题上摸不着头脑...我能够在没有.each循环的情况下让它工作,并且每个人都独一无二地创造一个...但是希望能够使这个通用并允许控制依赖于html上的data-widget-report属性。
这是正确的做法吗?
感谢任何帮助/指示...
答案 0 :(得分:1)
在var
和widget_class
前面添加$widget_report
,以便将其范围限定为函数而非全局。我认为这将解决您的问题。现在,即使在ajax调用完成之前,$widget_report
也会被最后一个小部件替换。
至于$(this)
无法正常工作,您必须在进行ajax调用之前将其分配给变量。
$('.widget-box').each(function() {
var widgetBoxElement = $(this);
var $widget_report = $(this).data('widget-report');
if ($widget_report !== undefined) {
$.ajax({
type: 'get',
url: '/admin/reports/' + $widget_report,
dataType: 'json',
success:
function(data) {
if (data.success) {
// use widgetBoxElement here instead of $(this)
}
}
});
}
});
