I am developing a module in jsp/servlet in which i need to use angular js. 我在jsp / servlet中开发一个模块,在其中我需要使用angular js。 how could i pass the value from input box value in function then how to send value in servlet also...!
我如何从函数中的输入框值中传递值,然后又如何在servlet中发送值...!
Here the example of code:- 这里的代码示例:-
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html ng-app="mehandi" >
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular.min.js">
</script>
<script>
var app = angular.module('mehandi', []);
app.controller('mhndiCtrl', function($http){
var xyz = this;
xyz.data = {}
xyz.swati = function($http){
}
})
</script>
</head>
<body ng-controller="mhndiCtrl as abc" >
<h1>Hello World!</h1>
<input type="text" ng-model="abc.data.myname">
{{abc.data}}
<button ng-click="abc.swati()" > </button>
</body>
</html>
You can invoke the function via ng-init
: in your html 您可以通过
ng-init
调用该函数:
ng-init="init('${userDTO.username}')"
So, in your *.js ng-controller it will be following: 因此,在您的* .js ng-controller中,它将如下所示:
$scope.init = function(username){
/*logic code*/
};
Use the name attribute of input for servlets 将输入的名称属性用于servlet
<input type="text" name="firstname">
You can then retrieve it using 然后,您可以使用
request.getParameter("firstname")
The angular part remains the same 角部分保持不变
<input type="text" name="firstname" ng-model="abc.data.myname">
Remember, angularjs is a client side javascript framework, hence server side bindings remains the same. 请记住,angularjs是客户端javascript框架,因此服务器端绑定保持不变。
