jQuery 遍历 JSON 对象

jQuery 遍历 JSON 对象

<一>:

$(document).ready(function() {$("#Link").click(function() {varobjson ="[{Title:'Sjr',Content:'Library',summary:'summary'},{Title:'Sjr',Content:'Library',summary:[{sum0:'sum0'},{sum0:'sum1'},{sum0:'sum2'}]},{Title:'Sjr',Content:'Library',summary:[{sum0:'sum0'},{sum0:'sum1'},{sum0:'sum2'}]}]";varobj = eval(objson);$(obj).each(function(index) {varval = obj[index];if(typeof(val.summary) =="object") {$(val.summary).each(function(ind) {alert(val.Title +" "+ val.Content +" "+ val.summary[ind].sum0);});}else{alert(val.Title +" "+ val.Content +" "+ val.summary);}});});});

<二>:

//下面使用each进行遍历

var obj = eval(writeMap);

$(obj).each( function (n) {

var val = obj[n];

if (typeof (val) == "object") {

$.each(val,function(index,realUrl) {

var lastid = $("#tcontent").find("tr:last").attr("id");

alert("=" + index + " ; = " + realUrl ");

onAddTR(index,realUrl,lastid);

var lastid = $("#tcontent").find("tr:last").attr("id");

});

}

});

<三>:

vararr = ['javascript','php','java','c++','c#','perl','vb','html','css','objective-c'];$.each(arr,function(key, val) {// firebug consoleconsole.log('index in arr:'+ key +", corresponding value:"+ val);// 如果想退出循环// return false;});
