[英]How to get json format string(extract from table)'s value
I have extract a json format data from a table like this: 我从这样的表中提取了json格式的数据:
[ { id:"3",
"Date Extracted":"12/3",
Experiment:"normal"},
{ id:"2",
"Date Extracted":"12/3",
Experiment:"powder",
Notes:"" },
{ id:"1",
"Date Extracted":"12/3",
Experiment:"fine",
Notes:"" }
]
And I have used function like below to get only the attributes of each id like "12/3","normal", not include the name like "Date Extracted", Experiments. 而且我已经使用如下函数来获取每个ID的属性,例如“ 12/3”,“普通”,而不包括名称“实验提取的日期”。 Somehow this does not work.
不知何故,这行不通。 but I have no idea how do it exactly in details.
但我不知道具体如何做。
var j = JSON.parse(data);
function(){
for(name in j.property.name)
console.log(j.property.value);
}
The extracted json data had some validation issues with the property names. 提取的json数据在属性名称方面存在一些验证问题。 You could verify your jsondata via jsonlint.com .
您可以通过jsonlint.com验证jsondata 。
So the json data should likely be: 因此json数据可能应该是:
var jsonData ='[{ "id":"3", "Date Extracted":"12/3","Experiment":"normal"}, { "id":"2","Date Extracted":"12/3","Experiment":"powder","Notes":"" },{ "id":"1","Date Extracted":"12/3","Experiment":"fine","Notes":"" }]';
Function: 功能:
var json = $.parseJSON(jsonData);
$(json).each(function(i,val){
$.each(val,function(name,value){
console.log(name + " : " + value);
});
});
You can't use "for" like that. 您不能这样使用“ for”。
var j = JSON.parse('[{ "id": "3", "Date Extracted": "12/3", "Experiment": "normal"}, { "id": "2", "Date Extracted": "12/3", "Experiment": "powder", "Notes": ""}, { "id": "1", "Date Extracted": "12/3", "Experiment": "fine", "Notes": ""}]');for(var i=0;i<j.length;i++){
var obj = j[i];
for(var key in obj){
var attrName = key;
var attrValue = obj[key];
console.log(attrValue);
}}
var data = [{ id: "3", "Date Extracted": "12/3", Experiment: "normal" }, { id: "2", "Date Extracted": "12/3", Experiment: "powder", Notes: "" }, { id: "1", "Date Extracted": "12/3", Experiment: "fine", Notes: "" }]; for (var i = 0; i < data.length; i++) { console.log("Date Extracted " + data[i]['Date Extracted'])//for index Date Extracted console.log("Experiment " + data[i]['Experiment'])//for index Experiment }

You can do using for loop like this 你可以像这样使用for循环
