Kendo-UI - 通过 JSON 创建动态表单 [英] Kendo-UI - Creating a Dynamic Form via JSON

问题描述

我已经能够使用 JSON 和 Kendo.Observable 成功构建动态表单，但是我无法在同一个 JSON 中成功初始化下拉列表值.我让它工作的唯一方法是在创建后将下拉列表绑定到单独的 json 请求.看下面的例子....

I have been able to successfully build out a dynamic form using JSON and Kendo.Observable, however I cannot initialize the dropdownlist values successfully within the same JSON. The only way I can get it to work is by binding the dropdown lists to a separate json request after creation. See the example below....

这是一些有效的 JSON 示例(无下拉列表)

Here is an example of some JSON that works (no dropdown list)

{"fields": [
                {"name" : "FirstName", "label" : "First Name", "type" : "text", "css" : "test"},    
                {"name" : "LastName", "label" : "Last Name", "type" : "text", "css" : "test"},
                {"name" : "Email", "label" : "Email", "type" : "text", "css" : "test"},
                {"name" : "Phone", "label" : "Phone", "type" : "text", "css" : "test"},
                {"name" : "Subscribed", "label" : "Subscribed", "type" : "checkbox", "css" : "test"}
                ]}

这是一个示例，我添加了一个下拉列表，不打算发布整个内容，我在下面尝试了许多不同的变体来尝试填充选择，但找不到任何有效的方法

Here is an example where I have added a dropdown, not going to post the whole thing, I have tried a number of different variations on the below to try and populate the select but can't find any that work

 {"fields": [
                {"name" : "Email", "label" : "Email", "type" : "text", "css" : "test"},
                {"name" : "FirstName", "label" : "First Name", "type" : "text", "css" : "test"},
                {"name" : "LastName", "label" : "Last Name", "type" : "text", "css" : "test"},
                {"name" : "Company", "label" : "Company", "type" : "text", "css" : "test"},
                {"name" : "ddlCountry", "label" : "Country", "type" : "select", "dataTextField" : "text", "dataValueField" : "value", "dataSource":[{"text" : "AF","value" : "Afghanistan"},{"text" : "AL","value" : "Albania"},{"text" : "DZ","value" : "Algeria"},{"text" : "AS","value" : "American Samoa"},{"text" : "AD","value" : "Andorra"},...etc...

这是绑定它的脚本

 $.ajax({
        url: "http://localhost/go/getformjson",
        type: "GET",
        dataType: "json",
        success: function (model) {
           // convert the JSON to observable object
            var viewModel = kendo.observable(model);
            // bind the model to the container
            kendo.bind($("#example"), viewModel);
        }
    });

推荐答案

需要指定data-text-field和data-value-field属性:

You need to specify the data-text-field and data-value-field attributes:

<select data-bind="source: options" data-text-field="ddltext" data-value-field="ddlvalue" />
