js 如何遍历jsonc对象?其实方法很简单。
比如有如下json对象:var obj ={”name”:”冯娟”,”password”:”123456″,”department”:”技术部”,”sex”:”女”,”old”:30};
代码如下:
for (var p in obj) {
str = str + obj[p] + ',';
return str;
}
综合实例:
var array = {
"a": "abc",
"b": [1, 2, 3, 4, 5, 6],
"c": 3,
"d": {
"name": "james",
"age": 28
},
"e": null,
"f": true
};
var arrayObj = {
"a": {
"name": "kobe",
"age": 34
},
"b": {
"name": "lofo",
"age": 28
}
};
//遍历array方式1
for (var x in array) {
if (typeof array[x] == 'object' && array[x] != null) {
for (var y in array[x]) {
alert("key = " + y + " value = " + array[x][y]);
}
} else {
alert("key = " + x + " value = " + array[x]); // 非array object
}
}
//遍历array方式2
$.each(array, function(k, v) {
var a = typeof(v);
//数组与对象为object类型,其他分别是string与number类型
//此时的k代表a、b、c、d,v代表对应的值
if (typeof(v) == "object") {
//获取数组与对象后,再去遍历这个数组与对象
$.each(v, function(k1, v1) {
window.alert("key = " + k1 + " value=" + v1);
});
} else {
window.alert("key = " + k + " value=" + v);
}
});
//遍历arrayObj方式1
for (var x in arrayObj) {
for (var key in arrayObj[x]) {
window.alert("key=" + key + " value=" + arrayObj[x][key]);
}
}
//遍历arrayObj方式2
$.each(arrayObj, function(key, value) {
$.each(value, function(k, v) {
window.alert("key=" + k + " value=" + v);
});
});
//遍历arrayObj方式3
$.each(arrayObj, function(key, value) {
window.alert("key=" + key + " valueName=" + value.name + " valueAge=" + value.age);
});
