如何将字符串转换为 javascript 中的 Object 数组

Question

I am getting response in a string array like this.

 {"columnModelObj":[{"filter":{"type":"list"},"multiValueTextData":true,"dataIndex":"_1","width":150,"text":"FILM"},{"filter":{"type":"list"},"multiValueTextData":true,"dataIndex":"_2","width":150,"text":"GENRE"},{"filter":{"type":"list"},"multiValueTextData":true,"dataIndex":"_3","width":150,"text":"LEAD STUDIO"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_4","showOriginalData":true,"width":150,"text":"AUDIENCE  SCORE %"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_5","showOriginalData":true,"width":150,"text":"PROFITABILITY"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_6","showOriginalData":true,"width":150,"text":"ROTTEN TOMATOES %"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_7","showOriginalData":true,"width":150,"text":"WORLDWIDE GROSS"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_8","showOriginalData":true,"width":150,"text":"YEAR"},{"filter":{"type":"list"},"multiValueTextData":true,"dataIndex":"_9","width":150,"text":"DATE"}],"recordModelObj":[{"name":"Film","type":"string"},{"name":"Genre","type":"string"},{"name":"Lead Studio","type":"string"},{"name":"Audience  score %","allowNull":true,"type":"number"},{"name":"Profitability","allowNull":true,"type":"number"},{"name":"Rotten Tomatoes %","allowNull":true,"type":"number"},{"name":"Worldwide Gross","allowNull":true,"type":"number"},{"name":"Year","allowNull":true,"type":"number"},{"name":"Date","type":"string"}]}

I have to make in to array object. Any possible idea how to make it.

Here is what I am doing but no luck.

var foo = col.split("\n").reduce(function(obj, str, index) {
  let strParts = str.split(":");
  if (strParts[0] && strParts[1]) { 
    obj[strParts[0].replace(/\s+/g, '')] = strParts[1].trim(); 
  }
  return obj;
}, {});

One simple code to fix your problems

data = ' {"columnModelObj":[{"filter":{"type":"list"},"multiValueTextData":true,"dataIndex":"_1","width":150,"text":"FILM"},{"filter":{"type":"list"},"multiValueTextData":true,"dataIndex":"_2","width":150,"text":"GENRE"},{"filter":{"type":"list"},"multiValueTextData":true,"dataIndex":"_3","width":150,"text":"LEAD STUDIO"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_4","showOriginalData":true,"width":150,"text":"AUDIENCE  SCORE %"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_5","showOriginalData":true,"width":150,"text":"PROFITABILITY"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_6","showOriginalData":true,"width":150,"text":"ROTTEN TOMATOES %"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_7","showOriginalData":true,"width":150,"text":"WORLDWIDE GROSS"},{"filter":{"type":"number"},"renderer":formatGridNumberColumn,"dataIndex":"_8","showOriginalData":true,"width":150,"text":"YEAR"},{"filter":{"type":"list"},"multiValueTextData":true,"dataIndex":"_9","width":150,"text":"DATE"}],"recordModelObj":[{"name":"Film","type":"string"},{"name":"Genre","type":"string"},{"name":"Lead Studio","type":"string"},{"name":"Audience  score %","allowNull":true,"type":"number"},{"name":"Profitability","allowNull":true,"type":"number"},{"name":"Rotten Tomatoes %","allowNull":true,"type":"number"},{"name":"Worldwide Gross","allowNull":true,"type":"number"},{"name":"Year","allowNull":true,"type":"number"},{"name":"Date","type":"string"}]}'

data = data.split("formatGridNumberColumn").join('"formatGridNumberColumn"')

data_object = JSON.parse(data)

and Data_object is the object you are looking for

you see the villain here is the formatGridNumberColumn which in not qouted " ". So the parsed result can never be a string.

Alone the formatGridNumberColumn is foreign to javascript.

for that reason I split the string by formatGridNumberColumn and joind it again by "formatGridNumberColumn". As it beacame a string now JSON can parse it.
