问题描述

我正在尝试使用角度推送功能,但它不起作用。



我想将字符串(或对象)添加到数组中。



我在Stack Overflow搜索了一些基本的例子,但是我找不到它。



任何人都可以更正我的代码或写一个非常基本的例子吗?



这是我的例子。

>

这是HTML代码:
$ b

 < ; form ng-controller =TestController as testCtrl ng-submit =testCtrl.addText(myText)> 
< input type =textvalue =Lets go>
<按钮类型=按钮>添加< /按钮>
< / form>

这是Java脚本代码:

 (function(){
var app ='测试控制器',函数(){
this.arrayText = {
text1:'Hello ',
text2:'world',
}

this.addText = function(text){
arrayText.push(this.text);
}
});
})();


解决方案

只推送ar的工作ray $。

使您的 arrayText 对象为Array对象。



试试像这样

JS

  this.arrayText = [{
text1:'Hello',
text2:'world',
}];

this.addText = function(text){
this.arrayText.push(text);
}
this.form = {
text1:'',
text2:''
};

HTML

 < div ng-controller =TestController as testCtrl> 
< form ng-submit =addText(form)>
< input type =textng-model =form.text1value =Lets go>
< input type =textng-model =form.text2value =让我们再去>
< input type =submitvalue =add>
< / form>
< / div>


I am trying to do use the angular push function but it is not working.

I want to add strings (or objects) into an array.

I searched for basic examples here at Stack Overflow but I couldn't find it.

Can anyone correct my code or write a very basic example?

Here is my example.

This is the HTML code:

<form ng-controller="TestController as testCtrl ng-submit="testCtrl.addText(myText)">
    <input type="text" value="Lets go">
    <button type="button">Add</button>
</form>

This is the Java Script code:

(function() {
    var app = angular.module('test', []);

    app.controller('TestController', function() {
        this.arrayText = {
            text1: 'Hello',
            text2: 'world',
        }

        this.addText = function(text) {
            arrayText.push(this.text);
        }
    });
})();

解决方案

Push only work for array .

Make your arrayText object to Array Object.

Try Like this

JS

this.arrayText = [{
  text1: 'Hello',
  text2: 'world',
}];

this.addText = function(text) {
  this.arrayText.push(text);
}
this.form = {
  text1: '',
  text2: ''
};

HTML

<div ng-controller="TestController as testCtrl">
  <form ng-submit="addText(form)">
    <input type="text" ng-model="form.text1" value="Lets go">
    <input type="text" ng-model="form.text2" value="Lets go again">
    <input type="submit" value="add">
  </form>
</div>
