3、Ext的Ajax提交
Ext的ajax提交：
handler:function() {
Ext.Ajax.request({
url:'common/ajax/login.jsp',
method:'POST',
params:{
'username':Ext.get("username").dom.value
vartext = eval("("+form.responseText+")");
alert('--------------2='+ text.msg);
},
failure:function() {
alert('--------------1');
}
})
}
//第二种方式
/*
handler:function() {
//document.location='index.html';
Ext.Msg.alert('成功', action.result.msg);
} else {
Ext.Msg.alert('登陆错误', action.result.msg);
}
},
failure:function(form, action) {
},
提交按钮：
handler:function() {
loginForm.form.submit();
}
2、默认提交方式(Ajax)
默认的提交方式：
handler:function() {
loginForm.form.doAction('submit', {
url:'/ext/common/ajax/login.jsp',
loginForm.form.doAction('submit', {
url:'/ext/common/ajax/login.jsp',
method:'POST',
params:'',
success:function(form, action) {
//alert(action.result);
if (action.result.msg == 'ok') {
response.setContentType("பைடு நூலகம்ext/html; charset=UTF-8");
String username = request.getParameter("username");
System.out.println("---->>>>>"+ username);
out.print("{success:true, msg:'ok'}");
method:'POST',
params:'',
success:function(form, action) {
//alert(action.result);
if(action.result.msg =='ok') {
//document.location='index.html';
Ext.Msg.alert('成功', action.result.msg);
//第三种方式
handler:function() {
Ext.Ajax.request({
url:'common/ajax/login.jsp',
method:'POST',
params:{
'username':Ext.get("username").dom.value
},
success:function(form, action) {
border:false,
formId:'form1',
name:'form1',
//onSubmit:Ext.emptyFn,
//submit: function(){
//this.getEl().dom.action = 'common/ajax/login.jsp'; //连接到服务器的url地址
}
}]
});
varwin =newExt.Window({
title:'window',
width:400,
frame:true,
border:false,
modal:true,
resizable:false,
items:loginForm
});
win.show();
});
1、正常form提交
这种方式需要在FormPanel对象中增加属性
fieldLabel:'用户名'
},{
name:'password',
inputType:'password',
fieldLabel:'密码'
},{
name:'code',
fieldLabel:'验证码',
anchor:'50%'
}],
buttons:[{
text:'登录',
type:'submit',
},
success:function(form, action) {
vartext = eval("("+form.responseText+")");
alert('--------------2='+ text.msg);
},
failure:function() {
alert('--------------1');
//this.getEl().dom.submit();
//alert(this.getEl().dom.elements.length);
//},
defaults:{
xtype:'textfield',
anchor:'90%'
},
items:[{
name:'username',
id:'username',
}else{
Ext.Msg.alert('登陆错误', action.result.msg);
}
},
failure:function(form, action) {
Ext.Msg.alert('警告','用户名或密码错误！');
}
})
}
服务端代码：
request.setCharacterEncoding("UTF-8");
onSubmit:Ext.emptyFn,
submit:function(){
this.getEl().dom.action ='common/ajax/login.jsp';//连接到服务器的url地址
this.getEl().dom.submit();
alert(this.getEl().dom.elements.length);
ExtJs表单提交
Ext.QuickTips.init();
Ext.BLANK_IMAGE_URL ='js/ext3/resources/s.gif';
Ext.onReady(function(){
varloginForm =newExt.FormPanel({
frame:true,
method:'POST',
Ext.Msg.alert('警告', '用户名或密码错误！');
}
})
}*/
//第一种方式
//handler:function() {
//loginForm.form.submit();
//}
},{
text:'取消',
handler:function() {
loginForm.form.reset();
