javascript - 如何将选择 "text"的 SELECT 框发送到按钮上的函数以使用 angular 进行 ng-click？

Question

好的，我有这个包含选择元素的 HTML 页面。该选择元素将有三个选择(请参阅下面这些选择的 $scope 定义...:

<div id="mainID" ng-controller="theController">
    <form name="assetTypeForm" class="form-horizontal" role="form" novalidate> 
        <select id="assetTypeSelect" name="asset.assetTypeList" style="width: 135px;"
            ng-model="asset.assetTypeList" 
            ng-options="option.name for option in assetTypeListOptions track by option.value"
            ng-change="regularAssetTypeToggleClick(asset)"
            class="form-control" required>
            <!-- This is a HACK to trick Angular to make the first option value = 0 -->
            <option value="" style="display: none;">Choose Type</option>
        </select>
        <button type="button" 
                ng-click="createAsset({{asset.assetTypeList}});" //This is the value I'm trying to pass...
                class="btn btn-primary btn-small"> 
                Create Asset
        </button>
    </form>
</div>

接下来在我的 Controller 中，我从按钮调用了这个函数:

$scope.createAsset = function (assetType) { //As you can see with assetType (arg) I want to pass what the user selected in the dropdown select box.

        $scope.$broadcast('show-errors-check-validity');
        console.log("The asset I want to create is: " + assetType);

        if ($scope.assetTypeForm.$invalid) {

            console.log("BUMMER! The assetTypeForm is NOT valid: " + $scope.assetTypeForm.$invalid);
            $scope.submitted = false;
            return;

        } else {

            //Open the dialog for creating a graphic element
            $scope.openCreateElement(assetType);

        }

    };

我有 assetType 下拉列表的定义:

    $scope.assetTypeListOptions = [
        {
            name: 'Choose Type...',
            value: 'choose'

        }, {
            name: 'EULA',
            value: 'eula'

        }, {
            name: 'GRAPHIC',
            value: 'graphic'

        }];
    //This sets the default for the list
    $scope.assetTypeList = $scope.assetTypeListOptions[0];

我在 console.log 中得到的是这样的:

The asset I want to create is: [object Object] <-- Here, is where either EULA, Graphic or Choose Type... where Choose Type... will throw an alert to tell the user, via show-errors{} that they NEED to select either EULA or Graphic.

就是这样....

谢谢

确定更新:作为回应评论:

所以，你的意思是；我可以将您在此处建议的内容传递给函数:[[[ $scope.assetTypeListOptions[$scope.asset.assetTypeList].value ]]] 到函数中:“createAsset({{asset.assetTypeList}});”像这样？

按顺序:

  ng-click="createAsset({{asset.assetTypeList}});"

您不需要在指令中使用 {{}}:

  ng-click="createAsset(asset.assetTypeList);"

但你甚至不需要通过它，因为你选择的模型总是可用的

$scope.asset.assetTypeList

---

还有你的初始化错误:

$scope.assetTypeList = $scope.assetTypeListOptions[0];

您使用 ng-model="asset.assetTypeList"，因此您应该初始化:

$scope.asset.assetTypeList = $scope.assetTypeListOptions[0];

确保$scope.asset之前已经初始化。

否则，使用 ng-model="assetTypeList"。
