在JavaScript / jQuery中,如何检索名称中包含空格的数据?

时间:2021-01-06 11:14:54

I am retrieving JSON using jQuery's getJSON call.

我正在使用jQuery的getJSON调用检索JSON。

My problem is that some of the fields in the returned JSON have spaces in them.

我的问题是返回的JSON中的一些字段中有空格。

How do I retrieve these values from the JSON without changing the source data? See line marked "ERROR" below:

如何在不更改源数据的情况下从JSON中检索这些值?请参阅下面标有“错误”的行:

$.getJSON(url, null, function(objData) {
  $.each(objData.data, function(i, item) {
    var zip = item.Zip;
    var fname = item.First Name; //ERROR
  });
});

Example JSON:

示例JSON:

jsonp123456789({"data":[{"Zip":"12345","First Name":"Bob"},{"Zip":"23456","First Name":"Joe"},{"Zip":"34567","First Name":"Bill"}]})

Thanks

谢谢

Array member access notation works on objects as well.

数组成员访问表示法也适用于对象。

$.getJSON(url, null, function(objData) {
  $.each(objData.data, function(i, item) {
    var zip = item.Zip;
    var fname = item['First Name'];
  });
});

You can use this for arbitrary strings (those that aren't legal identifiers) as well as variables.

您可以将此用于任意字符串(非合法标识符)以及变量。

var fieldName = "First Name";
var fname = item[fieldName];

$.getJSON(url, null, function(objData) {
  $.each(objData.data, function(i, item) {
    var zip = item.Zip;
    var fname = item["First Name"]; //Changed this
  });
});

reference the item using as a key instead of dot notation

使用键作为键而不是点表示法引用该项
