具有匹配值jquery的

Question

我有一个json文件，上面有球员的名字作为属性，值是是和否。我试图在每次(属性=‘是)的时候添加一个来计数，玩家会玩。

这里是json文件的一个示例

{"Wojciech Szczesny“：”是“，"Lukasz Fabianski”：“不”，"Emiliano Viviano":"no"，"Olivier Giroud":"yes"，"Per Mertesacker":"yes"，"Bacary Sagna":"yes"，"Laurent Koscielny":"no"，"Santi“：”yes“，"Mikel Arteta":"yes"，"Mesut \u00d6zil":"no"，"Kieran Gibbs":"yes"，Aaron Ramsey：”no“，Jack Wilshere：”no，““马蒂厄·弗拉米尼”：“是”，“托马斯·罗西基”：“是”，“是”，“卢卡斯·波多尔斯基”：“是”，“纳乔·蒙雷尔”：“不”，“西奥·沃尔科特”：“不”，“托马斯·韦尔马伦”：“是”，“卡尔·詹金森”：“不”，“亚历克斯·奥克斯莱德-张伯伦”：“不”，“不”，“塞尔日·格纳布里”：“不”，“金·达尔斯特罗姆”：“不”，“尼克·本特纳”：“不”，"Abou y“：”不“，”Abou y“：”no“，"Park no Young“：”no“，"Emmanuel Frimpong":"no"，"Yaya Sanogo":"no"，"Ryo Miyaichi":"no"，"Hector Bellerin":"no"，"Chuba Akpom":"no"，”萨克Hayden":"no"，"Gideon Zelalem":"no"，"Home":"home"，“结果”：“抽签”}

和这里我的Jquery代码

var count = 0;
    $.ajax({
        url:'ars.json',
        dataType:'json',
        cache: true,
  success: function(data) {
    $(data).each(function(index, value){
        if(Object.getOwnPropertyNames (value) == 'yes'){
            count++;
        }else{

        }
    });
    console.log(count);
}

var count = 0;
$.ajax({
  url:'ars.json',
  dataType:'json',
  cache: true,
  success: function(data) {
    for(var k in data){
      if(data.hasOwnProperty(k) && data[k]=="yes"){
         count++;
      }
    }
    console.log(count); // 11
  }
});

Answer 2

据我所知，你想用“是”的值来计算财产.您做了两个错误-这使您的代码完全错误: 1。您正在使用对象而不是这个循环，当然对象没有任何属性您正在寻找.2. $( data ).each只运行一次，因为数据不是数组，而是正确代码的单个对象：

success: function(data) {
  var count = 0;
  for(value in data) {
    if(data[value] == 'yes') {
      count++;
    } else {
      //
    }
});

Answer 3

尝试：

var v = {"Wojciech Szczesny":"yes","Lukasz Fabianski":"no","Emiliano Viviano":"no","Olivier Giroud":"yes","Per Mertesacker":"yes","Bacary Sagna":"yes","Laurent Koscielny":"no","Santi Cazorla":"yes","Mikel Arteta":"yes","Mesut \u00d6zil":"no","Kieran Gibbs":"yes","Aaron Ramsey":"no","Jack Wilshere":"no","Mathieu Flamini":"yes","Tomas Rosicky":"yes","Lukas Podolski":"yes","Nacho Monreal":"no","Theo Walcott":"no","Thomas Vermaelen":"yes","Carl Jenkinson":"no","Alex Oxlade-Chamberlain":"no","Serge Gnabry":"no","Kim Kallstrom":"no","Nicklas Bendtner":"no","Abou Diaby":"no","Park Chu-Young":"no","Emmanuel Frimpong":"no","Yaya Sanogo":"no","Ryo Miyaichi":"no","Hector Bellerin":"no","Chuba Akpom":"no","Isaac Hayden":"no","Gideon Zelalem":"no","Home":"home","Results":"draw"};

var count = 0;
$.each(v, function(k,v) {
    if (v == "yes") count++;
});

console.log(count);

演示

你的例子中的：

var count = 0;
$.ajax({
        url: 'ars.json',
        dataType: 'json',
        cache: true,
        success: function (data) {
            $.each(data, function (index, value) {
                if (value == "yes") count++;
            });
            console.log(count);
        }
});
