jquery驗證表單,jquery 驗證

jQuery為什么需要進行表單驗證

不是jQuery需要進行表單驗證，是網(wǎng)頁在提交數(shù)據(jù)的時候，為了減輕服務(wù)器的活，把能做的都在前端做了。

成都創(chuàng)新互聯(lián)于2013年成立，是專業(yè)互聯(lián)網(wǎng)技術(shù)服務(wù)公司，擁有項目網(wǎng)站設(shè)計、做網(wǎng)站網(wǎng)站策劃，項目實施與項目整合能力。我們以讓每一個夢想脫穎而出為使命，1280元祁東做網(wǎng)站,已為上家服務(wù),為祁東各地企業(yè)和個人服務(wù),聯(lián)系電話:13518219792

比如，用戶輸入一個手機號碼，如果該手機號碼格式是錯的，比如格式是158125238pp

然后前端人員又沒有對數(shù)據(jù)進行驗證，然后又提交到服務(wù)器那里去，很顯然這個手機號是錯的，服務(wù)器存儲這個手機號一點用處也沒有、、、

所以需要進行表單驗證

validate jquery怎么判斷一個表單是否通過驗證

validate jquery判斷一個表單是否通過驗證的方法是看頁面是否發(fā)生跳轉(zhuǎn)。

如果通過驗證那么跳轉(zhuǎn)頁面，否則停留在原頁面進行提示錯誤。

jquery在表單提交前有幾種校驗方法

在表單提交前進行驗證的幾種方式 .

在Django中，為了減輕后臺壓力，可以利用JavaScript在表單提交前對表單數(shù)據(jù)進行驗證。下面提供了有效的幾種方式（每個.html文件為一種方式）。

formpage1.html

復制代碼代碼如下:

!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ""

html xmlns=""

head

meta http-equiv="Content-Type" content="text/html; charset=utf-8" /

titleExample1/title

script type="text/javascript" src="/Resource/jquery-1.4.1.js"/script

script type="text/javascript"

function jump()

{

//清空表單所有數(shù)據(jù)

document.getElementById("firstname").value=""

document.getElementById("lastname").value=""

$("#firstnameLabel").text("")

$("#lastnameLabel").text("")

}

$(document).ready(function(){

$("#form1").bind("submit", function(){

var txt_firstname = $.trim($("#firstname").attr("value"))

var txt_lastname = $.trim($("#lastname").attr("value"))

$("#firstnameLabel").text("")

$("#lastnameLabel").text("")

var isSuccess = 1;

if(txt_firstname.length == 0)

{

$("#firstnameLabel").text("firstname不能為空！")

$("#firstnameLabel").css({"color":"red"});

isSuccess = 0;

}

if(txt_lastname.length == 0)

{

$("#lastnameLabel").text("lastname不能為空！")

$("#lastnameLabel").css({"color":"red"});

isSuccess = 0;

}

if(isSuccess == 0)

{

return false;

}

})

/script

/head

body

提交表單前進行驗證(方法一)
