如何将带有数组的JSON对象导入ajax自动完成响应？
如何将带有数组的JSON对象导入ajax自动完成响应？
提问于 2019-01-06 12:04:56
我正在开发的一个公司电子邮件生成应用程序有一个自动完成输入，可以将电子邮件主题数据自动填充到表单中。数据以JSON对象的形式返回，但是有两个对象值extraps和extraul包含多维数组。我能够在响应中获得普通键:值数据，但是我似乎不知道如何拉入数组，以便循环它们以更新表单的某些部分。
下面是一些JSON代码：
0:
emaildate: "2019-01-10"
extraps: Array(2)
0: {extrap: "test paragraph", position: 1}
1: {extrap: "another paragraph", position: 3}
length: 2
__proto__: Array(0)
extraul: Array(4)
0: {ulid: 1, position: 2, li: "list item 1", liposition: 1}
1: {ulid: 1, position: 2, li: "list item 2", liposition: 2}
2: {ulid: 1, position: 2, li: "list item something new", liposition: 3}
3: {ulid: 1, position: 2, li: "A new list item", liposition: 4}
length: 4
__proto__: Array(0)
id: 44
label: "Some Kind of Email Theme - 2019-01-10"
lastupdated: "2019-01-06 02:00:04"
store: "Premier"
themedesc: "Here's a description of the theme."
themeimage: null
themeincludeextrap: 1
themeincludeul: 1
themelink: "some-kind-of-email-theme"
themelinkinclude: 1
themename: "Some Kind of Email Theme"
themenotes: "Some notes about it"
themesortorder: 0
value: "Some Kind of Email Theme"
__proto__: Object
length: 1
__proto__: Array(0)下面是从autotheme.php引入的javascript：
//Autofill Theme Info based on text entry
$( "#themename" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "autotheme.php",
type: "GET",
dataType: "json",
data: {
q: request.term
},
success: function(data) {
console.log(data);
response($.map(data, function(item) {
return {
id: item.id,
value: item.value,
label: item.label,
themename: item.themename,
themenotes: item.themenotes,
themedesc: item.themedesc,
themeimage: item.themeimage,
themeincludeextrap: item.themeincludeextrap,
themeincludeul: item.themeincludeul,
themelinkinclude: item.themelinkinclude,
themelink: item.themelink,
themeextraps: item.extraps,
themeextraul: item.extraul
}
}))
},
error: function(errorThrown){
console.log(errorThrown);
console.log("There is an error with theme autocomplete.");
}
});
},
minLength: 2,
select: function(event, ui) {
if (ui.item) {
$this = $(this);
$('#themeid').val('');
$('#extratext').html('');
$('#themename').val(ui.item.themename);
$('#themenotes').val(ui.item.themenotes);
$('#themedesc').val(ui.item.themedesc);
var themeimage = ui.item.themeimage;
var themeincludeextrap = ui.item.themeincludeextrap;
var themeincludeul = ui.item.themeincludeul;
var themelinkinclude = ui.item.themelinkinclude;
var themeextraps = ui.item.extraps;
var themeextraul = ui.item.extraul;
if(themeextraps !== undefined) {
var extrapcount = themeextraps.length;
}
if(themeextraul !== undefined) {
var extraulcount = themeextraul.length;
}
if((themeextraps !== undefined) || (themeextraul !== undefined)) {
var extratextpositions = {};
$.each(themeextraps, function(i, themeextraps) {
extratextpositions[themeextraps.position] = 'p';
})
$.each(themeextraul, function(i, themeextraul) {
extratextpositions[themeextraul.position] = 'ul';
})
$.each(extratextpositions, function(key, value) {
if(extratextpositions[key] == 'p') {
addExtraP.call(this);
} else {
addExtraUl.call(this);
}
});
$('#themelink').val(ui.item.themelink);
if(themelinkinclude == 1) {
$('#themelinkinclude').prop("checked", true);
} else {
$('#themelinkinclude').prop("checked", false);
}
event.preventDefault();
}
},
open: function(event, ui) {
$(".ui-autocomplete").css("z-index", 1000);
},
complete: function(){
$("#themename").removeClass("ui-autocomplete-loading");
}
}
}); 我能够获得简单的key:value值，但是我没有为数组定义值。我确信我需要一种不同的方法来吸引他们，但我不知道如何，似乎在这里的其他帖子中找不到答案。任何帮助都将不胜感激！

多亏了@Bibberty的帮助，我找到了解决这个问题的方法。我不确定这是不是解决这个问题最优雅或最简单的方法，但它对我很有效。我从JSON数据值创建了一个数组，然后从数据数组中的数组创建变量，并将它们添加到响应返回值中。下面是新的函数代码(或者，至少是重要的部分)：
//Autofill Theme Info based on text entry
$( "#themename" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "autotheme.php",
type: "GET",
dataType: "json",
data: {
q: request.term
},
success: function(data) {
const results = data.map(function (value, label) {
return [value];
})
var extraps = results[0][0]['extraps'];
var extraul = results[0][0]['extraul'];
response($.map(data, function(item) {
return {
id: item.id,
value: item.value,
label: item.label,
themename: item.themename,
themenotes: item.themenotes,
themedesc: item.themedesc,
themeimage: item.themeimage,
themeincludeextrap: item.themeincludeextrap,
themeincludeul: item.themeincludeul,
themelinkinclude: item.themelinkinclude,
themelink: item.themelink,
extraps: extraps,
extraul: extraul
}
}))
$("#themename").removeClass("ui-autocomplete-loading");
},
error: function(errorThrown){
console.log(errorThrown);
console.log("There is an error with theme autocomplete.");
}
});
},
minLength: 2,
select: function(event, ui) {
if (ui.item) {
$this = $(this);
console.log(ui.item.extraps);
$('#themeid').val('');
$('#extratext').html('');
$('#themename').val(ui.item.themename);
$('#themenotes').val(ui.item.themenotes);
$('#themedesc').val(ui.item.themedesc);
var themeimage = ui.item.themeimage;
var themeincludeextrap = ui.item.themeincludeextrap;
var themeincludeul = ui.item.themeincludeul;
var themelinkinclude = ui.item.themelinkinclude;
var themeextraps = ui.item.extraps;
var themeextraul = ui.item.extraul;
if(themeextraps !== undefined) {
var extrapcount = themeextraps.length;
}
if(themeextraul !== undefined) {
var extraulcount = themeextraul.length;
}
