請問小程序 新聞內(nèi)頁中，如何調(diào)用出自定義字段？

比如我要調(diào)用出縮略圖字段 thumb、多圖字段 images、

模塊為案例 anli，是使用news的show去改的

show.js為

var WxParse = require('../../wxParse/wxParse.js');

var app = getApp();
var http_url = app.globalData.http_api + "s=anli&c=show";
http_url += '&api_call_function=';
var member_url = app.globalData.http_api + "s=api&app=anli&c=module&api_auth_code=" + wx.getStorageSync('member_auth') + "&api_auth_uid=" + wx.getStorageSync('member_uid');


Page({
data: {
id: '',
content: '',
supports: 0,
upsImg: "../../icons/ups.png",
collectImg: "../../icons/collect.png",
},
onLoad: function (options) {

app.showModel();
var self = this;
wx.request({
url: http_url,
data: {
id: options.id
},
header: {
'content-type': 'application/json'
},
dataType: 'json',
method: 'GET',
success: function (res) {


if (res.data.code == 1) {
// 是否收藏
wx.request({
url: member_url + '&m=is_favorite',
data: {
id: options.id
},
header: {
'content-type': 'application/json'
},
dataType: 'json',
method: 'GET',
success: function (sc) {
if (sc.data.code == 1) {
self.setData(
{
collectImg: "../../icons/collect-active.png",
})
}
}
});

// 格式化文章內(nèi)容
var article = res.data.data.content;

WxParse.wxParse('data', 'html', article, self);

self.setData({
content: res.data.data,
supports: res.data.data.support,
id: options.id
})
wx.hideToast();
} else {
wx.showModal({
showCancel: false,
content: res.data.msg
})
}



}
})
},
getCommentList: function () {//評論跳轉(zhuǎn)

wx.navigateTo({
url: '../news/comment?id=' + this.data.content.id
})
},


up: function () {//點(diǎn)贊

var self = this;
wx.request({
url: member_url + '&m=digg&value=1',
data: {
id: self.data.id
},
header: {
'content-type': 'application/json'
},
dataType: 'json',
method: 'GET',
success: function (sc) {
if (sc.data.code == 1) {
wx.showToast({
icon: 'success',
title: sc.data.msg,
duration: 2000
});
self.setData(
{
supports: sc.data.data,
})
} else {
wx.showModal({
showCancel: false,
content: sc.data.msg
})
}
}
});
},
collect: function () {//收藏
var self = this;
wx.request({
url: member_url + '&m=favorite',
data: {
id: self.data.id
},
header: {
'content-type': 'application/json'
},
dataType: 'json',
method: 'GET',
success: function (sc) {
if (sc.data.code == 1) {
wx.showToast({
icon: 'success',
title: sc.data.msg,
duration: 2000
});
if (sc.data.msg == '收藏成功') {
self.setData(
{
collectImg: "../../icons/collect-active.png",
})
} else {
self.setData(
{
collectImg: "../../icons/collect.png",
})
}
} else {
wx.showModal({
showCancel: false,
content: sc.data.msg
})
}
}
});

}


})

show.wxml使用這個去調(diào)的，但是調(diào)不到

<image class="l_xqsa" mode="widthFix" src="{{content.thumb}}"></image>
