Jquery 遍历 Json 的实现代码
代码如下:
/* author: liulf function: var __db_cpcj=vCpcj; var __db_cp=vCp; var vCp={"cppage":[ {"cpdh":"A01000101","page":"1","ca":"1309-36-0","mc":"硫铁矿","ename":"Pyrite","bm":"黄铁矿"}, {"cpdh":"A01000201","page":"1","ca":"1309-36-0","mc":"硫精砂","ename":"Pyrite concentrate;Sulfur concentrate","bm":""}, {"cpdh":"A01000202","page":"1","ca":"1309-36-0","mc":"硫精矿粉","ename": "Powdered pyrite concentrate;Pyrites concentrate,powder;Sulfur concentrate,powder","bm":"硫精矿"},{"cpdh":"A02000101","page":"1","ca":"","mc":"磷矿石","ename":"Phosphorus ore","bm":""}, {"cpdh":"A02000111","page":"2","ca":"","mc":"磷矿砂","ename":"Phosphorite grit","bm":""}, {"cpdh":"A02000201","page":"2","ca":"","mc":"磷矿粉","ename":"Phosphate rock powder","bm":""},{"cpdh":"A03000101","page":"2","ca":"12447-04-0","mc":"硼矿石","ename":"Ascharite;Boric ore","bm":"硼镁矿"}, {"cpdh":"A04000101","page":"2","ca":"","mc":"钾长石","ename":"Potash feldspar;Potassium feldspars","bm":""}, {"cpdh":"A04000201","page":"2","ca":"12003-63-3","mc":"长石粉","ename":"Feldspar powder","bm":""}, {"cpdh":"A04000301","page":"2","ca":"","mc":"光卤石","ename":"Carnallite","bm":""} ]} */function ObjSearch() { this.kw = ''; this.searchCpcj = function() { $(vCpcj).each(function() {}); } this.searchCp = function() { // var json = eval(vCp.cppage) // for(var i=0; i' + content.cpdh + ' '); }); }}
js 如何遍历jsonc对象？其实方法很简单。
比如有如下json对象：var obj ={”name”:”冯娟”,”password”:”123456″,”department”:”技术部”,”sex”:”女”,”old”:30};
遍历方法：代码如下:
for (var p in obj) { str = str + obj[p] + ','; return str;}综合实例：
var array = { "a": "abc", "b": [1, 2, 3, 4, 5, 6], "c": 3, "d": { "name": "james", "age": 28 }, "e": null, "f": true};var arrayObj = { "a": { "name": "kobe", "age": 34 }, "b": { "name": "lofo", "age": 28 }};//遍历array方式1for (var x in array) { if (typeof array[x] == 'object' && array[x] != null) { for (var y in array[x]) { alert("key = " + y + " value = " + array[x][y]); } } else { alert("key = " + x + " value = " + array[x]); // 非array object }}//遍历array方式2$.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 $.each(v, function(k1, v1) { window.alert("key = " + k1 + " value=" + v1); }); } else { window.alert("key = " + k + " value=" + v); }});//遍历arrayObj方式1for (var x in arrayObj) { for (var key in arrayObj[x]) { window.alert("key=" + key + " value=" + arrayObj[x][key]); }}//遍历arrayObj方式2$.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);});var UserList = [ { "UserID": 11, "Name": { "FirstName": "Truly", "LastName": "Zhu" }, "Email": "" }, { "UserID": 12, "Name": { "FirstName": "Jeffrey", "LastName": "Richter" }, "Email": "" }, { "UserID": 13, "Name": { "FirstName": "Scott", "LastName": "Gu" }, "Email": "" }]$.each(UserList, function(k, v) { $.each(v, function(k1, v1) { if (typeof(v1) == "object") { $.each(v1, function(k2, v2) { window.alert("key=" + k2 + " value=" + v2); }); } else { window.alert("key=" + k1 + " value=" + v1); } });});var userArray = [ { "UserID": 11, "Name": { "FirstName": "Truly", "LastName": "Zhu" }, "Email": "" }, { "UserID": 12, "Name": { "FirstName": "Jeffrey", "LastName": "Richter" }, "Email": "" }, { "UserID": 13, "Name": { "FirstName": "Scott", "LastName": "Gu" }, "Email": "" }];for (var i in userArray) { for (var k in userArray[i]) { if (typeof userArray[i][k] == "object" && userArray[i][k] != null) { for (var j in userArray[i][k]) { window.alert("key=" + j + "--value=" + userArray[i][k][j]); } } else { window.alert("key=" + k + "--value=" + userArray[i][k]); } }}
