如何根据数字显示评分

node.js jquery php javascript

user5405873 · 技术社区 · 8 年前

我现在的处境是 data database 这样地

var data = [  {name:'Alpha Hotel',price:400,star:3},
              {name:'Beta Hotel',price:600,star:4},
              {name:'Gamma Hotel',price:450,star:5},
           ];

我想展示同样多 rating 作为我的 star

例如 {name:'Alpha Hotel',price:400,star:3} 我的 评级 3 1

以下是我尝试过的: https://jsfiddle.net/ewL4wLvh/2/

使用 loop 对于表单 star

Array#fill - fill()

Array#reduce - reduce()

var data = [{
  name: 'Alpha Hotel',
  price: 400,
  star: 3
}, {
  name: 'Beta Hotel',
  price: 600,
  star: 4
}, {
  name: 'Gamma Hotel',
  price: 450,
  star: 5
}, ];

var htmlConstructed = '';
$.each(data, function(i, val) {
  var starStr = Array(val.star).fill(null).reduce((a) => a + '<i class="fa fa-star" aria-hidden="true" style="color:#D91E18;"></i>', '');
  htmlConstructed += '<p>Name : ' + val.name + '</p>' + '<p>Price : ' + val.price + '</p>' + 'Rating :<span>' + starStr + '</span><hr/>';
});
$('#content-area').append(htmlConstructed);

在构造HTML时,需要重复 spans
您可以使用这个巧妙的技巧来实现这一点,而无需使用循环:

htmlConstructed += '<p>Name : '+val.name+'</p>'+
    '<p>Price : '+val.price+'</p>'+
    'Rating :'+new Array(val.star + 1).join('<span><i class="fa fa-star" aria-hidden="true" style="color:#D91E18;"></i></span>')+
    '<hr/>';

Array.join

var data = [  {name:'Alpha Hotel',price:400,star:3},
          {name:'Beta Hotel',price:600,star:4},
          {name:'Gamma Hotel',price:450,star:5},
       ];

var htmlConstructed = '';
 $.each(data,function(i,val){        
      htmlConstructed += '<p>Name : '+val.name+'</p>'+'<p>Price : '+val.price+'</p>'+'Rating :<span>'+
      Array(val.star).join('<i class="fa fa-star" aria-hidden="true" style="color:#D91E18;"></i>')
  +'</span><hr/>';

  });

  $('#content-area').append(htmlConstructed);

您可以使用这个简单的解决方案。

var data = [  {name:'Alpha Hotel',price:400,star:3},
                  {name:'Beta Hotel',price:600,star:4},
                  {name:'Gamma Hotel',price:450,star:5},
               ];

        var htmlConstructed = '';
         $.each(data,function(i,val){
             // console.log(val.name);
             var rating='';
             for(var i=0;i<val.star;i++){
                    rating = rating +'<span><i class="fa fa-star" aria-hidden="true" style="color:#D91E18;"></i></span>';
             }
              htmlConstructed += '<p>Name : '+val.name+'</p>'+'<p>Price : '+val.price+'</p>'+'Rating :'+rating+'<hr/>';


     });

     $('#content-area').append(htmlConstructed);

使用此代码,

var data = [  {name:'Alpha Hotel',price:400,star:3},
              {name:'Beta Hotel',price:600,star:4},
              {name:'Gamma Hotel',price:450,star:5},
           ];

    var htmlConstructed = '';
     $.each(data,function(i,val){
         // console.log(val.name);

          htmlConstructed += '<p>Name : '+val.name+'</p>'+'<p>Price : '+val.price+'</p>'+'Rating :'+ addStar(val.star) +'<hr/>';

 });

 function addStar(rating){
 var returnString = '';
 for(var i=0;i< rating;i++ )
 returnString = returnString + '<span><i class="fa fa-star" aria-hidden="true" style="color:#D91E18;"></i></span>';

 return returnString;

 }

 $('#content-area').append(htmlConstructed);
