Esw*_*zle 0 javascript jquery json decimal
我正在制作一个从JSON文件动态提取数据的表,我需要能够将值更改为两位小数。根据我已有的代码,这甚至可能吗?我想做的事的例子:
--7更改为7.00
--3922.2更改为3922.20
--89.2823更改为89.28
非常感谢!
这是我的HTML:
<table id="reportTable" class="reportTable">
<th>Timer Name</th>
<th>Daily Percentile 90th</th>
<th>Daily Percentile 50th</th>
<th>Min Percentile 90th</th>
<th>Max Percentile 90th</th>
<th>Daily Average</th>
</table>

//THIS CODE GETS THE JSON, ALPHABETIZES THE INFO, AND POPULATES THE TABLE.
var information = $.ajax({
type: "GET",
url: "http://websiteIgetmyJSONfrom.com",
dataType: "json",
success: function (information) {
information.sort( function( a, b ) {
a = a.timerName.toLowerCase();
b = b.timerName.toLowerCase();
return a < b ? -1 : a > b ? 1 : 0;
});
$.each(information, function(i, item) {
var $tr = $('<tr class="clickable">').append(
$('<td align="left">').text(item.timerName),
$('<td>').text(item.daily_percentile_90th),
$('<td>').text(item.daily_percentile_50th),
$('<td>').text(item.min_percentile_90th),
$('<td>').text(item.max_percentile_90th),
$('<td>').text(item.daily_average)).appendTo('#reportTable');
