我正在尝试与json合作,我几乎拥有我需要的东西.我正在显示正确的信息,但我必须将数组中的每个项目传递给变量,然后打印变量.我想显示每个数组中的所有项目.我正在使用的json数据来自一个发票应用程序(
www.curdbee.com),我正在尝试显示客户的每张发票.我想要显示的数据是每个订单项,订单项价格和总金额.这是我的代码:
$(document).ready(function() {
$.getJSON('https://nspirelab.curdbee.com/invoices.json?api_token=__token__',function(data){
$.each(data,function(index,item){
var total = item.invoice.total_billed;
var lineItemName1 = item.invoice.line_items[0].name_and_description;
var lineItemName2 = item.invoice.line_items[1].name_and_description;
var lineItemPrice1 = item.invoice.line_items[0].price;
var lineItemPrice2 = item.invoice.line_items[1].price;
$('#results').append('<div class="lineItem"><ul><li>' + lineItemName1 + lineItemPrice1 + '</li><li>' + lineItemName2 + lineItemPrice2 + '</li><li>' + total + '</li></ul></div>');
});
});
});
解决方法
嵌套循环(或者,在jQuery中,嵌套的$.each())将完成这项工作:
$.getJSON('https://nspirelab.curdbee.com/invoices.json?api_token=&client=104929',function(data){
$.each(data,item){
// create an empty ul (initially disconnected from the DOM)
var $ul = $("<ul/>");
// iterate over the line items
$.each(item.invoice.line_items,function(i,lineItem) {
// create an li element with the line details and append
// it to the ul
$ul.append( $("<li/>").html(lineItem.name_and_description + lineItem.price) );
});
// add the totals to the end of the ul
$ul.append( $("<li/>").html(item.invoice.total_billed) );
// create a new div,append the ul to it,and append the div to results
$('#results').append( $('<div class="lineItem"/>').append($ul) );
});
});
