Question

我已经制作了这个JSON。但我发现了这个错误

 a +="<div class=\"back\">"
                + "<a href=\"[[--CatAddress, s_tk, tplid:8270--]]\"><img src=\"[[--ImgRootDir--]]resource/image/button_back.png\" width=\"85px\" /></a>"

这是json

nodes: [
{
id: "2014_2012.json_0_0",
image: "_1396278834_af_org.png",
question: "1. What is this ?",
answer: "EXX",
hint: "asdadsadsadasdasdaads"
},
{
id: "2014_2012.json_0_0",
image: "_1396278834_af_org.png",
question: "1. What is this ?",
answer: "EXX",
hint: "asdadsadsadasdasdaads"
},

Answer 1

好的，做了一些假设，但这很有效：http://jsfiddle.net/sp1nf731/3/

您是否正确引用了json变量？

var x = { nodes: [
{
id: "2014_2012.json_0_0",
image: "_1396278834_af_org.png",
question: "1. What is this ?",
answer: "EXX",
hint: "asdadsadsadasdasdaads"
},
{
id: "2014_2012.json_0_0",
image: "_1396278834_af_org.png",
question: "1. What is this ?",
answer: "EXX",
hint: "asdadsadsadasdasdaads"
} 
] };

console.log( x.nodes[1].image );

这对我来说很好用

Answer 2

我不知道你是如何获得节点的，但如果内联你需要

var nodes=[
  { .... },
  { .... },
  { .... }
]; // no comma on the last

这是一个缩短jQuery代码的建议

$(function() {
  var $rowa=$("<tr/>"), $rowb=$("<tr/>"),
  $.each(nodes,function(i,node) {
    if (i>0 && i%5==0) {
      $("#table1 tbody").append($rowa).append($rowb);
    }
    $rowa.append(getSubsHTML(node.image, jsonStage.indexOf("2014_2012.json_0_"+i),i);
    $rowb.append(getStageHTML(jsonStage.indexOf("2014_2012.json_0_"+i));
  });        
  // here you may test if i%5 !=0  and add the last rows
});

JSON TypeError：无法读取未定义的属性“image”
