具有多个动态选择框angularjs [英] Having multiple dynamic select boxes angularjs

问题描述

我使用

到目前为止，这个功能和显示都正确。但是，我不知道如何捕获我的 processImport（）函数中的数据。

绑定，但由于用户可以从选择框中添加/删除属性，因此无法预构建选择框。因为每个csv可以有不同数量的列，我需要重复每个列。

有关如何捕获这里提交的数据的任何建议？

解决方案

因此，对于那些努力工作的人来说，这真的不是那么复杂。是的，我知道我现在在说，但是当你看到的解决方案，这很简单。

所以我有一个这样的对象：

  var $ scope.rows = {
'header'：帐户代码，
'header_safe'：帐户代码，
'options'：[Ignore，Cellphone Number，First Name，Full Name，Last Name，Title，Add Attribute]，
'值：WELG01，ABDO01，ABOO01，ABOO2，ABOO02，ABOU01，ABRA03，ABRA01，ABRA02，ACKE04
}，{
'header'：客户名称
'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，如果你看到上面的图片，你会认为我的问题中的图像显示什么。要让这些下拉列表工作，这是我的HTML看起来像：

 < table class =table table-hover ; 
< tr> 
< th ng-show =has_headerclass =col-md-4>标题< / th> 
< th class =col-md-4>属性< / th> 
< th class =col-md-4>值示例< / th> 
< / tr> 
< tr ng-repeat =row in rows> 
< td ng-show =has_header> {{row.header}}< / td> 
< td> 
< select class =form-controlng-model =select [row.header_safe]ng-options =option for row.options>< / select& 
< / td> 
< td> {{row.values}}< / td> 
< / tr> 
< / table> 
  

然后，在我的表单提交，我只有一个 processImport / code>函数。该函数如下所示：

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

并且捕获我的所有数据。

可以使用更清晰的示例此处。感谢原作者，因为他完全回答了我的问题。

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

This is my form:

<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>

The HTML gives this result:

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

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.

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

解决方案

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.

So I have an object like this:

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"
}

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>

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

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

And that catches all my data.

A cleaner example is available here. Thanks to the original author, as he definitively answered my question.
