JS怎么遍历json数组

。

用 for in 循环遍历var str = '[{"name":"宗2瓜","num":"1","price":"122"},{"name":"宗呱呱","num":"1","price":"100"}]';var xqo = eval('(' + str + ')');for(var i in xqo){alert(xqo[i].name);}。

Js 怎么遍历json对象所有key及根据动态key获取值

typescript教程视频，typescript高级教程。

varsmsTypeDesc={"4":"回访短信","3":"邮件短信","aa":"测试短信"};functionEnumaKey(){for(varkeyinsmsTypeDesc){alert(key);}}functionGetVal(){varkey=prompt("请输入要查询的key","4");if("undefined"==typeof(smsTypeDesc))return;if("undefined"==typeof(smsTypeDesc[key])){alert("输入的key:"+key+"，在json对象中不存在！

");return;}alert("您输入的key是："+key+"，该key所对应的值是："+smsTypeDesc[key]);}functionGetValByKey(){alert();}Json对象：varsmsTypeDesc={"4":"回访短信","3":"邮件短信","aa":"测试短信"};。

Js 怎么遍历json对象所有key及根据动态key获取值

js怎么遍历json数组对象，如何遍历出content里面的数值，格式如下

js遍历json数组，求大神指导（2）

。

varjson1=[{"age":5,"num":2,"people":3,"class":9},{"age":1,"num":3,"people":2,"class":8},{"age":4,"num":6,"people":5,"class":3}];varjson2=[{"field":"age","typle":"sum","title":"ss"},{"field":"num","typle":"sum","title":"ss"},{"field":"people","typle":"sum","title":"ss"},{"field":"class","typle":"nosum","title":"ss"}];//如上json1、json2两个数组，拿json1里age、num等属性去json2里遍历，若json2里field的值和json1的属性相等并且其typle的值为num，就计算json1里该属性的和最终再拼接成下面的样子//varjson3=[{"name":"求和","age":10,"num":11,"people":10}];functiontest(json1,json2){ varresult=[],resultJson={"name":"求和"}; vargetSum=function(field){ varsum=0; for(varsinjson1){ sum+=json1[s][field]||0; } returnsum; } for(varpinjson2){ if(json2[p]["typle"]=="sum"){ $.extend(resultJson,$.parseJSON('{\"'+json2[p]["field"]+'\":'+getSum(json2[p]["field"])+'}')); } } (resultJson); returnresult;}json3=test(json1,json2);//检查一下结果temp=""for(vartinjson3[0]){ temp+=t+"="+json3[0][t]+",";}alert(temp.slice(0,-1));//显示：name=求和,age=10,num=11,people=10。

js遍历某一列json数据和

用JS原生的方法即可，不过没在JSON上看到数值啊，我帮你取到了数组，剩下的自己操作下就可以了。

Documentvar JosnInfo = {"sites": [{"title": "批次数量","Field": "pcsl","ReadOnly": "readonly='readonly'","Hidetd": "true","tdEvent": " οnclick='openPC(this)'","tdClass": "tdspbh","txtAlign": ""},{"title": "编号","Field": "spbh","ReadOnly": "readonly='readonly'","Hidetd": "false","tdEvent": " ","tdClass": "tdspbh","txtAlign": ""},{"title": "名称","Field": "spmc","ReadOnly": "readonly='readonly'","Hidetd": "false","tdEvent": " οnkeydοwn='SXZY(this)' ","tdClass": "tdspmc","txtAlign": ""},{"title": "规格","Field": "ggxh","ReadOnly": "readonly='readonly'","Hidetd": "false","tdEvent": " οnkeydοwn='SXZY(this)' ","tdClass": "tdggxh","txtAlign": ""},{"title": "产地","Field": "spcd","ReadOnly": "readonly='readonly'","Hidetd": "false","tdEvent": " οnkeydοwn='SXZY(this)' ","tdClass": "tdcd","txtAlign": ""},{"title": "单位","Field": "spdw","ReadOnly": "readonly='readonly'","Hidetd": "false","tdEvent": " οnkeydοwn='SXZY(this)' ","tdClass": "tddw","txtAlign": "text-align:center;"},{"title": "数量","Field": "spsl","ReadOnly": "","Hidetd": "false","tdEvent": " οnpaste='return false' οnkeydοwn='return check(event)' οnkeydοwn='SXZY(this)' οnblur='sl_onblur(this)' ","tdClass": "tdsl","txtAlign": "text-align:right;"},{"title": "单价","Field": "spdj","ReadOnly": "","Hidetd": "false","tdEvent": " οnpaste='return false' οnkeydοwn='return check(event)' οnkeydοwn='SXZY(this)' οnblur='dj_onblur(this)'","tdClass": "tddj","txtAlign": "text-align:right;"}]};JosnInfo = JSON.stringify(JosnInfo);var text = JSON.parse(JosnInfo);(text.sites);。

js遍历json对象读数据

。

varjsondata=yourdata;for(varxinjsondata){document.write(x+"="+jsondata[x]);}如果是jsonarray就外面套一层for即可varjsonarray=yourarray;for(vari=0;i。

如何在js中遍历后台传的json 50

。

$(document).ready(function(){ vardata="{root:[{limCode:'YGMK1'},{limCode:'YGZZ2'},{limCode:'YGZJ2'},{limCode:'YGZJ2'}]}"; vardatajson=eval("("+data+")"); $.each(,function(i,item){ alert("limCode:"+item.limCode); }); });。
