开发中表单提交是很常见的,表单的提交方式也多种方式。
1.使用submit按钮提交表单 <input type="submit"/>
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>form表单提交方式</title>
</head>
<body>
<form action="demo_form.asp" method="post">
First name:<br>
<input type="text" name="firstname" value="Mickey"><br>
Last name:<br>
<input type="text" name="lastname" value="Mouse"><br><br>
<input type="submit" value="提交">
</form>
<script>
/*这里是提交表单前的非空校验*/
$("form").submit(function () {
var first = $("input[name='firstname']").val();
var last = $("input[name='lastname']").val(); if (first == "" || first == null || first == undefined) {
alert("first");
return false;/*阻止表单提交*/
} else if (last == "" || last == null || last == undefined) {
alert("last");
return false;/*阻止表单提交*/
} else {
alert("提交");
return true;
}
})
</script>
</body>
</html>
当您点击提交按钮,表单数据会被发送到名为demo_form.asp的页面。submit按钮提交表单,表单直接被提交了!当然提交表单前可能需要进行验证,可以根据自己的需求做表单提交【校验请看Jquery部分代码】
如果不喜欢用$(selector).submit(function) 提交方法,也可以使用 onsubmit="return function()"方法进行提交验证。代码如下:
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>form表单提交方式</title>
</head>
<body>
<form id="Form" action="" method="post" onsubmit="return checkForm();">
<!--直接提交-->
<input id="first" type="text" name="dingdanhao"><input id="chaxun" type="submit" value="查询"><br>
First name:<br>
<input id="last" type="text" name="firstname"><br>
Last name:<br>
<input type="text" name="lastname"><br><br>
<input id="tj" type="submit" value="提交">
</form>
<script src="jquery.js"></script>
<script>
/*这里是提交表单前的非空校验*/
function checkForm () {
var first = $("input[name='firstname']").val();
var last = $("input[name='lastname']").val(); if (first == "" || first == null || first == undefined) {
alert("first不能为空");
return false;/*阻止表单提交*/
} else if (last == "" || last == null || last == undefined) {
alert("last不能为空");
return false;
} else {
alert("提交")
return true;
} }
</script>
</body>
</html>
注释:
onsubmit直接写false表单还是会被提交。
表单的onsubmit事件句柄(比如:onsubmit="return false")不会执行。 不能保证由其一定会被HTML用户代理调用。
如果一个表单空间(比如一个submit类型的按钮)的name 或者id值为"submit",则它将覆盖表单的submit方法。
2.使用button按钮提交表单 <input type="button"/>
(1)可以直接将 上述方法1中的<input type="submit" value="提交">直接换成<input type="button" value="提交">
(2) 方法差不多 没啥区别 直接贴代码
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>form表单提交方式</title>
</head>
<body>
<form id="Form" action="" method="post" >
<!--直接提交-->
<input type="text" name="dingdanhao"><input id="chaxun" type="submit" value="查询"><br>
First name:<br>
<input type="text" name="firstname"><br>
Last name:<br>
<input type="text" name="lastname"><br><br>
<input id="tj" type="button" value="提交" onclick="checkForm();">
</form>
<script src="jquery.js"></script>
<script>
/*这里是提交表单前的非空校验*/
function checkForm () {
var first = $("input[name='firstname']").val();
var last = $("input[name='lastname']").val(); if (first == "" || first == null || first == undefined) {
alert("first");
return false;/*阻止表单提交*/
} else if (last == "" || last == null || last == undefined) {
alert("last");
return false;
} else {
alert("提交")
$("#Form").submit();
} }
</script>
</body>
</html>
3.利用js进行表单提交,将form表单进行标记,将form表单中的某个元素设置点击事件,点击时调用js函数,再用js:如 $("#id").submit();等方法提交表单。
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>form表单提交方式</title>
</head>
<body>
<form id="Form" action="" method="post" onsubmit="return checkForm();">
<!--直接提交-->
<input id="first" type="text" name="dingdanhao"><input id="chaxun" type="submit" value="查询"><br>
First name:<br>
<input id="last" type="text" name="firstname"><br>
Last name:<br>
<input type="text" name="lastname"><br><br>
<button type="button" onclick="subForm();">js提交</button>
</form>
<script src="jquery.js"></script>
<script>
/*这里是提交表单前的非空校验*/
function checkForm () {
var first = $("input[name='firstname']").val();
var last = $("input[name='lastname']").val(); if (first == "" || first == null || first == undefined) {
alert("first不能为空");
return false;/*阻止表单提交*/
} else if (last == "" || last == null || last == undefined) {
alert("last不能为空");
return false;
} else {
alert("提交")
return true;
} }
function subForm(){
$("#Form").submit();
}
</script>
</body>
</html>
4.<input type="image" src=""> 图片提交表单,将input的属性设置为image时,点击图片也可触发form表单的提交。
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>form表单提交方式</title>
</head>
<body>
<form id="Form" action="" method="post" onsubmit="return checkForm();">
<!--直接提交-->
<input id="first" type="text" name="dingdanhao"><input id="chaxun" type="submit" value="查询"><br>
First name:<br>
<input id="last" type="text" name="firstname"><br>
Last name:<br>
<input type="text" name="lastname"><br><br>
<input type="image" src="btn.png" style="width: 50px;height: 50px">
</form>
<script src="jquery.js"></script>
<script>
/*这里是提交表单前的非空校验*/
function checkForm() {
var first = $("input[name='firstname']").val();
var last = $("input[name='lastname']").val(); if (first == "" || first == null || first == undefined) {
alert("first不能为空");
return false;
/*阻止表单提交*/
} else if (last == "" || last == null || last == undefined) {
alert("last不能为空");
return false;
} else {
alert("提交")
return true;
}
} </script>
</body>
</html>
