像这样的东西:
var objects = [
{
"foo" : "bar",
"bar" : "sit"
},
{
"foo" : "lorem",
"bar" : "ipsum"
},
{
"foo" : "dolor",
"bar" : "amet"
}
];
var results = [];
var toSearch = "lo";
for(var i=0; i<objects.length; i++) {
for(key in objects[i]) {
if(objects[i][key].indexOf(toSearch)!=-1) {
results.push(objects[i]);
}
}
}
结果数组将包含所有匹配的对象。
如果您搜索“lo”,结果将类似于:
[{ foo="lorem", bar="ipsum"}, { foo="dolor", bar="amet"}]
新版本 - 添加了修剪代码,确保结果集中没有重复的代码。
function trimString(s) {
var l=0, r=s.length -1;
while(l < s.length && s[l] == ' ') l++;
while(r > l && s[r] == ' ') r-=1;
return s.substring(l, r+1);
}
function compareObjects(o1, o2) {
var k = '';
for(k in o1) if(o1[k] != o2[k]) return false;
for(k in o2) if(o1[k] != o2[k]) return false;
return true;
}
function itemExists(haystack, needle) {
for(var i=0; i<haystack.length; i++) if(compareObjects(haystack[i], needle)) return true;
return false;
}
var objects = [
{
"foo" : "bar",

];
function searchFor(toSearch) {

if(!itemExists(results, objects[i])) results.push(objects[i]);
}
}
}
return results;
}
console.log(searchFor('lo '));
