拥有多种动态选择框angularjs [英] Having multiple dynamic select boxes angularjs

问题描述

我建立使用 Papaparse 一个CSV重要的联系方式。该网站上的角运行。

I built a csv contact importer using Papaparse. The site runs on angular.

这是我的方式：

<div ng-show="import_file_selected">
    <form ng-submit="processImport()" name="importForm">
        <div class="row">
            <div class="col-md-12">
                <table class="table table-hover">
                    <tr>
                        <th ng-show="has_header" class="col-md-4">Header</th>
                        <th class="col-md-4">Attribute</th>
                        <th class="col-md-4">Value Sample</th>
                    </tr>
                    <tr ng-repeat="row in rows">
                        <td ng-show="has_header">{{row.header}}</td>
                        <td>
                            <select class="form-control" name="{{row.header}}">
                                <option value="">Ignore</option>
                                <option ng-repeat="attribute in attributes" value="{{attribute.key}}">{{attribute.val}}</option>
                                <option value="add">Add Attribute</option>
                            </select>
                        </td>
                        <td>{{row.values}}</td>
                    </tr>
                </table>
            </div>
        </div>
        <div class="row">
            <div class="col-md-6 form-group col-md-offset-3">
                <button class="btn btn-primary btn-block" type="submit">Save Import</button>
            </div>
        </div>
    </form>
</div>

该HTML给出了这样的结果：

The HTML gives this result:

到目前为止，这一切功能和显示正常。不过，我不知道如何捕捉数据在我的 processImport（）功能。

So far, this all functions and displays correctly. However, I have no idea how to capture the data in my processImport() function.

我想用绑定的，但是从选择框，因为用户可以添加/删除属性，我不能pre-构建选择框。并且由于每个CSV可以有不同数量的列，我需要与每列有重复

I thought of using binding, but since a user can add/remove attributes from the select box, I can't pre-build the select box. And since each csv can have a different number of columns, I need to repeat with each column there is.

我如何能捕捉到这里提交的数据有什么建议？请让我知道我是否应该添加任何东西。

Any suggestions on how I can capture the data submitted here? Please let me know if I should add anything else.

推荐答案

因此​​，对于那些像这样苦苦挣扎，这真的不是那么复杂。是的，我知道我在说，现在，但当你看到的解决方案，它是pretty简单。

So for those struggling with something like this, it's really not that complex. Yes, I know I'm saying that now, but when you see the solution, it's pretty simple.

所以我有这样的对象：

var $scope.rows = {
    'header': "Account Code",
    'header_safe': "Account Code",
    'options': ["Ignore", "Cellphone Number", "First Name", "Full Name", "Last Name", "Title","Add Attribute"],
    'values: "WELG01, ABDO01, ABOO01, ABOO2, ABOO02, ABOU01, ABRA03, ABRA01, ABRA02, ACKE04"
},{
    'header': "Customer Name"
    'header_safe': "Customer Name"
    'options': ["Ignore", "Cellphone Number", "First Name", "Full Name", "Last Name", "Title","Add Attribute"],
    'values': ", Abdool, Aboo, Aboobaker, Aboobaker, Abouchabki, Abraham Thato, Abrahams, Abrams, Ackerman Rulaine"
}

其中，如果你看到上面你会承认什么会显示在我的问题图像中的图像。为了得到这些工作的下拉菜单，这是我的HTML是什么样子：

Which, if you see the image above you'd recognise as what is displayed in the image in my question. To get those dropdowns working, this is what my HTML looks like:

<table class="table table-hover">
    <tr>
        <th ng-show="has_header" class="col-md-4">Header</th>
        <th class="col-md-4">Attribute</th>
        <th class="col-md-4">Value Sample</th>
    </tr>
    <tr ng-repeat="row in rows">
        <td ng-show="has_header">{{row.header}}</td>
        <td>
            <select class="form-control" ng-model="select[row.header_safe]" ng-options="option for option in row.options"></select>
        </td>
        <td>{{row.values}}</td>
    </tr>
</table>

然后，在我的表单提交，我只是有一个 processImport（）功能。这个函数是这样的：

Then, on my form submit, I just have a processImport() function. That function looks like this:

$scope.processImport = function() {
    console.log($scope.select);
}

和映入我的所有数据。
