我正在学习Laravel 5.2和vue.js,并且不熟悉语法,问题是:
如何获取下面表单元素的所有值,并使用vue.js将它们发送给控制器?
包括文本,选择,文本区域,文件输入,无线电,复选框。
PS:
html演示中有一个插件,它的功能是压缩选定的图像。

关于它是否真的是Laravel,我有点不确定 - &gt; Vue设置你正在寻找,因为你的问题中绝对没有Laravel或Vue代码,这是非常广泛的,但这是一个基本的入门模板。我几乎在每个项目中使用以下内容。
<强> Laravel 强>
创建路线 - routes / web.php:
Route::post('/myform', 'FormControntroller@submitForm');
创建您的控制器和方法 - app / http / controllers / FormController.php
class FormController extends App\Controllers\Controller {
public function submitForm()
{
var_dump(request->all());
}
}
创建您的输入视图 - resources / views / app.blade.php
<html>
<head>
<title>Minimal Vue Example</title>
</head>
<body>
<div id="app">
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.1/vue.min.js"></script>
<script src="/js/main.js"></script
</body>
</html>
<强> Vue公司 强>
main.js
import Vue from 'vue'
import Resource from 'vue-resource'
import Router from 'vue-router'
import Root from './components/Root.vue'
Vue.use(Router)
Vue.use(Resource)
var router = new Router({
history: true,
});
router.map({
'/': {
component: Root
},
});
// Start up our app
router.start(Root, '#app');
创建根组件 - resources / views / assets / js / components / Root.vue
<template>
<form v-on:submit.prevent="submitForm">
<input type="text" v-model="formData.username"/>
<input type="text" v-model="formData.password"/>
</form>
</template>
<script>
export default {
data: function() {
return {
formData: {
username: null,
password: null
}
}
},
methods: {
submitForm: function() {
this.$http.post('/myform', this.formData).then(function(response) {
alert('Yay, my form was posted!');
});
}
}
}
</script>
此时您需要在资产上运行网络包,请参阅Laravel Documentation上的Elixir。
同样,在没有提供太多背景知识的情况下,您已经提出了一个非常广泛的问题,但这会让您前进。
注意:以上代码在Vue 1.X上运行代码,版本2略有不同。
有关Vue和Laravel的进一步帮助,请参阅Laravel Documentation。
