从jQuery中的JSON值创建字符串 [英] create string from JSON values in jQuery
问题描述
我想从JSON对象创建一个ISBN字符串,以搜索Google图书中的多本图书.
我可以通过使用以下路径解析Google图书的JSON来获取ISBN:
volumeInfo.industryIdentifiers[0].identifier
(我在这里是为了获得一个简单的书单: jsfiddle.net/LyNfX )>
如何将每个值串在一起以获得此查询结构,其中每个ISBN前面都带有"isbn:",而在第一个之后则用"OR"分隔
https://www.google.com/search?btnG=Search+Books&tbm=bks&q=Springfield+isbn:1416549838+OR+isbn:068482535X+OR+isbn:0805093079+OR+isbn:0306810328
从称为list
的ISBN字符串数组开始:
list.map(function(v){return "isbn:"+v;}).join("+OR+")
关于建立您的ISBN列表,我理解是您的industryIdentifiers
中的identifier
道具(如果industryIdentifier
是真诚的Array
):
var list = [];
volumeInfo.industryIdentifiers.forEach(function(e,i){list.push(e.identifier);});
您也可以一次构建最后一个字符串,而根本不构建数组,但这意味着需要额外的逻辑来防止插入额外的定界符(+OR+
是定界符)
var output = "";
volumeInfo.industryIdentifiers.forEach(function(e,i){output += "isbn:"+e.identifier+"+OR+";});
output.slice(0,-4); // clear out last +OR+
I'd like to create a string of ISBNs from a JSON object to search multiple books in Google Books.
I can get the ISBNs by parsing Google Books' JSON with this path:
volumeInfo.industryIdentifiers[0].identifier
(Here I'm doing that to get a simple book list: jsfiddle.net/LyNfX )
How do I string together each value in order to get this query structure, where each ISBN is preceded by "isbn:", and after the first one they are separated by "OR"
https://www.google.com/search?btnG=Search+Books&tbm=bks&q=Springfield+isbn:1416549838+OR+isbn:068482535X+OR+isbn:0805093079+OR+isbn:0306810328
Starting from an array of ISBN strings called list
:
list.map(function(v){return "isbn:"+v;}).join("+OR+")
As for building your list of ISBN's which I understand to be the identifier
prop in your industryIdentifiers
(if industryIdentifier
is a bona fide Array
):
var list = [];
volumeInfo.industryIdentifiers.forEach(function(e,i){list.push(e.identifier);});
You could also just build the final string in one fell swoop and not build an array at all, but this means extra logic to prevent inserting an extra delimiter (+OR+
being the delimiter)
var output = "";
volumeInfo.industryIdentifiers.forEach(function(e,i){output += "isbn:"+e.identifier+"+OR+";});
output.slice(0,-4); // clear out last +OR+
