这里是我的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

当我得到它时，你想要计算具有价值的属性＆＃39;是＆＃39; ... 你犯了两个错误 - 这使你的代码完全错误： 1.你在循环中使用Object代替这个，当然Object没有你要寻找的任何属性...... 2. $（data）.each只运行一次，因为数据不是数组而是单个对象现在为正确的代码：

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);

在您的情况下：

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); } });
