提问by Muaz Khan
I'm using asp.net mvc - ajax with jQuery... I've a model type named "Books" that contains a property "TableOfContents" this property contains data in the following format:
我正在使用 asp.net mvc - ajax 和 jQuery ......我有一个名为“ Books”的模型类型,它包含一个属性“ TableOfContents”,这个属性包含以下格式的数据:
TableOfContents = "1,2,4,6,9,17,28";
Json action method, that reuturn Book object look like this:
Json 动作方法,返回的 Book 对象如下所示:
public JsonResult GetBook(int id) {
return Json(_bookRepository.Current(id), .....AllowGet);
}
Following style of list images that I want to display.
遵循我要显示的列表图像的样式。
In C# (Razor) I can do this,
在 C# (Razor) 中,我可以做到这一点,
var splitted = Model.TableOfContents.Split(‘,');
@foreach(var number in splitted) {
<li><img src=”@Url.Content(“~/Content/Images/img-“ + number + “.gif”)” /> </li>
}
This code 100% works and shows images as shown in the above image.
此代码 100% 有效并显示如上图所示的图像。
The same thing I want to done with jQuery because I'm using ASP.NET MVC Ajax with jQuery. Here is the jQuery script through with I get data from MVC via jQuery.
我想用 jQuery 做同样的事情,因为我使用 ASP.NET MVC Ajax 和 jQuery。这是我通过 jQuery 从 MVC 获取数据的 jQuery 脚本。
<script type="text/javascript">
function GetBook(id) {
var url = '@Url.Content("~//Monthly/CurrentBook?id=")' + id;
$.post(url,
null,
function (book) {
$('#bookResult' + book.ID).html(
'<a href="@Url.Content("~/BookDetails/")' + book.ID + '">Click to View Details</a>'
+ '<div><p style=" text-align:center;">'
+ '<a href="' + monthly.URL + '"><button style="background-image:url(@Url.Content("~/Content/Images/download-pdf.gif")); width:200px; height:70px;" /></a>'
+ '**<!-- Here I want to use jQuery Code for displaying Table of content Images -->**'
+ '</p></div>');
},
'json'
);
}
</script>
I used jQuery code like this:
我使用了这样的 jQuery 代码:
$.each(book.TableOfContents.split(','), function(number) {
+ '<li><img src="img-' + number + '.gif" /></li>'
}
But it displays result as: "1,2,3,17,90" (in string format instead of displaying images)
但它将结果显示为:“1,2,3,17,90”(以字符串格式而不是显示图像)
In ASP.NET MVC Razor, I can display list of images like this:
在 ASP.NET MVC Razor 中,我可以显示这样的图像列表:
var splitted = Model.TableOfContents.Split(‘,');
@foreach(var number in splitted) {
<li><img src=”@Url.Content(“~/Content/Images/img-“ + number + “.gif”)” /> </li>
}

If you have
如果你有
var book={TableOfContents:"1,2,4,6,9,17,28"};
as your object with data then in <head>
add:
作为带有数据的对象,然后<head>
添加:
$(function(){
$('#list').empty();
var TableOfContentsSplit=book.TableOfContents.split(',');
$.each(TableOfContentsSplit,function(number){
$('#list').append('<li><img src="img-'+TableOfContentsSplit[number]+'.gif" /></li>\n');
});
});
and in <body>
add:
并<body>
补充说:
<ul id="list"></ul>
At the end you'll get:
最后你会得到:
<ul id="list">
<li><img src="img-1.gif"></li>
<li><img src="img-2.gif"></li>
<li><img src="img-4.gif"></li>
<li><img src="img-6.gif"></li>
<li><img src="img-9.gif"></li>
<li><img src="img-17.gif"></li>
<li><img src="img-28.gif"></li>
</ul>
