如何在ASP.NET MVC 5中使用带有razor语法的jquery? [英] how to use jquery with razor syntax in asp.net mvc 5?

问题描述

我需要使用jQuery动态添加一些元素.因此，我在互联网上进行了查找，发现

I need to use jQuery to add some elements dynamically. So I looked up in the internet and I found this. It is nice and working when there is plain html elements inside single quotes. I need to use razor syntax with jQuery.

我知道jQuery是用户端，而razor是服务器端.它们不能组合在一起.我在这里问是因为我需要知道如何实现这一目标.

I understand that jQuery is user side and razor is server side. They cannot be combined together. I am asking here because I need to know how do i achieve this.

我无法使用的jQuery如下:

My not working jQuery is as follows:

<script type="text/javascript">  
    $(document).ready(function () {  
        $(document).on("click", ".btnPlus", function () { 
        var html = '<div class="form-group">'+
                '@Html.LabelFor(model => model.transaction_item, "transaction_item", htmlAttributes: new { @class = "control-label col-md-2" })'+ 

                '<div class="col-md-4">'+
                    '@Html.DropDownList("transaction_item", null, htmlAttributes: new { @class = "form-control" })'+
                    '@Html.ValidationMessageFor(model => model.transaction_item, "", new { @class = "text-danger" })'+
                '</div>'+

                '<div class="col-md-6"><input type="button" class="BtnPlus" value="+" /></div>'+

            '</div>'
        $("#trItem").append($(html))
    };
});

我的目标类似于

My aim is similar to the tutorial - to add elements dynamically. Here I am adding a label and dropdown on the click of button. How do I achieve this?

推荐答案

您不能使用JQuery添加Razor元素，因为正如您已经说过的那样，JQuery是客户端库，而使用Razor语法的ASP.NET是服务器端脚本语言.

You cannot add Razor elements using JQuery because, as you have stated, JQuery is a client side library and ASP.NET using Razor syntax is a server side scripting language.

如果要添加使用Razor语法创建的元素，则将隐藏元素添加到页面并使用JQuery添加将其克隆到DOM.

If you want to add elements created using Razor syntax then add a hidden element to the page and use JQuery to add a clone of it to the DOM.

这样的事情应该使您了解我的意思:

Something like this should give you an idea of what I mean:

@Html.DropDownList("transaction_item", null, htmlAttributes: new { @class = "form-control", @id = 'template-ddl' })

$("#trItem").append($('#template-ddl').clone());
