Question

我的索引上有一个表单，它接受一个名称的输入。在使用ng-submit提交名称后，我想隐藏表单，然后显示另一个当前未隐藏的div。我已经尝试在表单中添加一个按钮来设置ng-click并在点击时显示但是无法使其工作（我把按钮拿出来）并且只是提交输入。

HTML

<form name="add-name" id="add-name" ng-submit="mainCtrl.addName()">
    <input type="text" class="enter-name" placeholder="Enter your name here..." ng-model="mainCtrl.newName.name">
</form>

<!--- this part should be hidden, but should show when form is submitted --->
<div class="steptwo">
    <h4 class="steptwo-text">{{ mainCtrl.newName.name }}</h4>
</div>

控制器

app.controller('mainController', function($scope) {

    this.newName = { name: '' };

    this.names = this.names || [
        { name: ' ' },
    ];

    this.addName = function() {

        this.names.push({
            name: this.newName.name
        });

        this.newName.name = null;
    };
    return this;
});

非常感谢任何解释或帮助。

Answer 1

您可以使用ng-if或ng-show/hide指令来显示和隐藏div取决于表达式...

所以首先将此指令添加到要显示和隐藏的部分html中，并为它们提供相同的表达式...

<form name="add-name" id="add-name" ng-submit="mainCtrl.addName()" ng-hide="mainCtrl.hideForm">
    <input type="text" class="enter-name" placeholder="Enter your name here..." ng-model="mainCtrl.newName.name">
</form>

<!--- this part should be hidden, but should show when form is submitted --->
<div class="steptwo" ng-show="mainCtrl.hideForm">
    <h4 class="steptwo-text">{{ mainCtrl.newName.name }}</h4>
</div>

然后在你的控制器中设置hideForm变量为true，这样表格将被隐藏，第二步将显示...

this.addName = function() {

    this.names.push({
        name: this.newName.name
    });

    this.newName.name = null;

    // hide form
    this.hideForm = true;

};

HTML：

 <form name="add-name" id="add-name" ng-submit="mainCtrl.addName()" ng-if="hide">
    <input type="text" class="enter-name" placeholder="Enter your name here..." ng-model="mainCtrl.newName.name">
</form>

<!--- this part should be hidden, but should show when form is submitted --->
<div class="steptwo" ng-if="!hide">
    <h4 class="steptwo-text">{{ mainCtrl.newName.name }}</h4>
</div>

控制器：

app.controller('mainController', function($scope) {
$scope.hide = false;
this.newName = { name: '' };

this.names = this.names || [
    { name: ' ' },
];

this.addName = function() {

    this.names.push({
        name: this.newName.name
    });

    this.newName.name = null;
};
$scope.hide = true;
return this;

}）;

您可以在ng-if标记上使用ng-show或ng-hide或<form>，并控制来自控制器的值。

HTML文件：

<form name="add-name" id="add-name" ng-submit="mainCtrl.addName()" ng-hide="hide">
    <input type="text" class="enter-name" placeholder="Enter your name here..." ng-model="mainCtrl.newName.name">
    <input type="button" ng-click="{{hide=true}}">
</form>

<!--- this part should be hidden, but should show when form is submitted --->
<div class="steptwo" ng-show="hide">
    <h4 class="steptwo-text">{{ mainCtrl.newName.name }}</h4>
</div>

JavaScript文件：

app.controller('mainController', function($scope) {
    $scope.hide = false;
    this.newName = { name: '' };

    this.names = this.names || [
        { name: ' ' },
    ];

    this.addName = function() {

        this.names.push({
            name: this.newName.name
        });

        this.newName.name = null;
    };
    return this;
});
