[英]dynamic bootstrap carousel items
如何循環創建動態自舉輪播項目?
這是json:
"pro": {
"52": {
"product_id": "52",
"category_id": "109",
"name": "Morder Rock Double 3"
},
"54": {
"product_id": "54",
"category_id": "109",
"name": "Morder Rock Double 5"
},
"57": {
"product_id": "57",
"category_id": "109",
"name": "Morder Rock Double 8"
},
"59": {
"product_id": "59",
"category_id": "109",
"name": "Morder Rock Double 10"
},
"61": {
"product_id": "61",
"category_id": "109",
"name": "Mordern Single Cutaway 12"
},
"62": {
"product_id": "62",
"category_id": "109",
"name": "Mordern Single Cutaway 13"
}
}
這是我的代碼
var itemslist = '';
var product_Data ='';
itemslist += '<div class="item active"><div class="container"><div class="row">'
$.each(nvalue.pro, function (lkey, lvalue) {
product_Data += '<div class="col-md-3">\n\
' + lvalue.name + '<img class="img-responsive"
src="image/product_images/1.jpg" alt="Los Angeles" /> \n\
</div>';
});
itemslist += product_Data + '</div></div></div>';
我需要這樣:
<div class="item active">
<div class="container">
<div class="row">
<div class="col-md-3">
Morder Rock Double 3<img class="img-responsive" src="image/product_images/1.jpg" alt="Los Angeles">
</div>
<div class="col-md-3">
Morder Rock Double 5<img class="img-responsive" src="image/product_images/1.jpg" alt="Los Angeles">
</div>
<div class="col-md-3">
Morder Rock Double 8<img class="img-responsive" src="image/product_images/1.jpg" alt="Los Angeles">
</div>
<div class="col-md-3">
Morder Rock Double 10<img class="img-responsive" src="image/product_images/1.jpg" alt="Los Angeles">
</div>
</div>
</div>
</div>
<div class="item">
<div class="container">
<div class="row">
<div class="col-md-3">
Mordern Single Cutaway 12<img class="img-responsive" src="image/product_images/1.jpg" alt="Los Angeles">
</div>
<div class="col-md-3">
Mordern Single Cutaway 13<img class="img-responsive" src="image/product_images/1.jpg" alt="Los Angeles">
</div>
</div>
</div>
</div>
您需要添加一個索引,以跟蹤添加了多少個元素,然后關閉一個滑塊元素,然后每四張圖像打開下一個。
我在下面的代碼中添加了一個變量i
,並使用系數檢查它是否為4的倍數以識別何時執行此操作。
i % 4
模數%
將第一個數字(在這種情況下為變量i
)除以隨后的數字,並返回余數 。
然后,您可以在if
語句中使用它,就像變量的模數沒有余數一樣,它可以被4整除,因此必須是4的倍數。
// Check every fourth
if ( i % 4 == 0) {
...
}
注意:我添加了更多的JSON數據,以證明該代碼對於大型數據集仍然有效。
