Question

I have a JSON file which contains data like the following:

{"posts": [ 
    { "title":"1", "url":"n1.png" }, 
    { "title":"2", "url":"n2.png" }, 
    { "title":"3", "url":"n3.png" }, 
    { "title":"4", "url":"n4.png" }, 
    { "title":"5", "url":"n5.png" }, 
    { "title":"6", "url":"n6.png" }, 
    { "title":"7", "url":"n7.png" }, 
    { "title":"8", "url":"n8.png" }, 
    { "title":"9", "url":"n9.png" }, 
    { "title":"10", "url":"n10.png" }
]}

I need to filter title by range with two text boxes: from and to.

Answer 1

I use Linq JS on my current project and it works really well for filtering data.

http://jslinq.codeplex.com/

var posts = [ 
    { "title":"1", "url":"n1.png" }, 
    { "title":"2", "url":"n2.png" }, 
    { "title":"3", "url":"n3.png" }, 
    { "title":"4", "url":"n4.png" }, 
    { "title":"5", "url":"n5.png" }, 
    { "title":"6", "url":"n6.png" }, 
    { "title":"7", "url":"n7.png" }, 
    { "title":"8", "url":"n8.png" }, 
    { "title":"9", "url":"n9.png" }, 
    { "title":"10", "url":"n10.png" }
];

var filteredPost = JSLINQ(posts)
                   .Where(function(item){ return item.title >= "textBox1Value" && item.title <= "textBox2Value"; });
