Question

我有一个数组数组，实际上是一系列表行。

0: Array[5]
0: ""
1: ""
2: "Is there at least one teacher or other adult in this school that you can talk to if you have a problem?"
3: ""
4: ""

1: Array[5]
0: ""
1: ""
2: "Yes"
3: "No"
4: "Not sure"

2: Array[5]
0: "Grade"
1: "6th"
2: "55%"
3: "20%"
4: "25%"

如果我遇到某些内容，即＆＃34;？＆＃34;我想将该行分配给新的JSON对象。我使用forEach循环遍历数组，如下所示：

function parseRow(element, index, array) {
    element.forEach(parseCell);
  }
function parseCell(element, index, array) {
    if (element.indexOf("?") > -1) { // if it is a question
      //do something to tell indicate this is a question row

    }  else { 
      // table cell
    }
  }

我需要在目标中更加明确。我有一个行值（作为数组），其中一些包含一个表定义问题，其中一些是标题行，其中一些是表行。我想吐出一个像这样格式化的JSON对象：

 {
"question": "Is there at least...",
"Category": "Overall",
"Division" : "All",
"Yes" : "65.00%",
"No": "11.70%",
"Not Sure" : "23.30%",
},
{
"question": "Is there at least...",
"Category" : "Grade",
"Division" : "6th",
"Yes" : "65.00%",
"No": "11.70%",
"Not Sure" : "23.30%",
},
{
"question": "Is there at least...",
"Category" : "Grade",
"Division" : "7th",
"Yes" : "65.00%",
"No": "11.70%",
"Not Sure" : "23.30%",
},

JSON对象可能更嵌套，这似乎是最容易处理的构建。

您可以使用可以返回对象的map函数，以便从元素数组中获取一系列问题：

function parseRow(element, index, array) {
   var questions = element.map(function(el,i){
       if(el.indexOf("?") > -1){
          return el;
       }
   });
}

这将为您提供一系列包含问题的元素。
