在普通的JavaScript,假設你已經有一個div聲明爲<div id=divId></div>
:
var images = {
"imageUrl":"http://server06.amobee.com/aspx/nadav/test/banner320x50.png",
"expandedImageUrl":"http://server06.amobee.com/aspx/nadav/test/banner320x320.jpg"
};
var div = document.getElementById('divId');
var img = document.createElement('img');
img.setAttribute('src', images.imageUrl);
div.appendChild(img);
img.onclick=function(){
this.src=images.expandedImageUrl;
};

如果具有類似於images
對象對象的數組,就可以循環到創建它們。它比它似乎沒有價值的,由於「閉合效應」,這就是爲什麼我包括代碼:
var images = [
{ "imageUrl":"http://dystroy.org/re7210/img/crevettes-ail-courgettes-2-750.jpg",
"expandedImageUrl":"http://dystroy.org/re7210/img/crevettes-ail-courgettes-750.jpg"},
{ "imageUrl":"http://dystroy.org/re7210/img/cote-beuf-champis-02-850.jpg",
"expandedImageUrl":"http://dystroy.org/re7210/img/cote-beuf-champis-05-850.jpg"},
{ "imageUrl":"http://dystroy.org/re7210/img/onglet-truffes-850-02.jpg",
"expandedImageUrl":"http://dystroy.org/re7210/img/onglet-truffes-850-05.jpg"}
];
var div = document.getElementById('divId');
for (var i=0; i<images.length; i++) {
var image =images[i];
var img = document.createElement('img');
img.setAttribute('src', image.imageUrl);
div.appendChild(img);
(function(expandedImageUrl){ // we embed the expanded URL in a closure to avoid having the value at end of loop used
img.onclick=function(){
this.src=expandedImageUrl;
};
})(image.expandedImageUrl);
}

這裏是一個允許點擊切換兩個圖像的版本:

謝謝了很多,但怎麼改回預覽圖像? – shaharnakash
我爲此編輯了一個新版本。 –
非常感謝:) – shaharnakash
