javascript - 将 viewbag 转换为 javascript 数组

Question

我想从 ViewBag.mytags 获取数据到一个 Javascript 数组，但是我无法实现这一点

$(function () {
    var sampleTags = new Array();
    var array = @Html.Raw(Json.Encode(@ViewBag.mytags));
    for(var i =0; i<array.length;i++){
        sampleTags[i] = array[i];
    }  
    $('#singleFieldTags').tagit({
        availableTags: sampleTags,
        singleField: true,
        singleFieldNode: $('#mySingleField')
    });
}

这是我的 Controller

ViewBag.mytags = mp3.TagSuggestion();

这是我的模型

public IQueryable<string> TagSuggestion() 
{ 

    IQueryable<string> tabs = from s in db.tblTags select s.Title; 

    return tabs; 

} 

Answer 1

请按照以下步骤

public IList<string> TagSuggestion() 
{ 
    IQueryable<string> tabs = from s in db.tblTags select s.Title; 
    return tabs.toList(); 
}

内部 MVC Controller :

ViewBag.mytags = mp3.TagSuggestion().toList();

在 View 中:

<script>
    $(function () {
        var sampleTags = new Array();
        var array = @Html.Raw(Json.Encode(@ViewBag.mytags));
        for(var i =0; i<array.length;i++){
            sampleTags[i] = array[i];
        }  

        $('#singleFieldTags').tagit({
            availableTags: sampleTags,
            singleField: true,
            singleFieldNode: $('#mySingleField')
        });
    });
</script>
