提交表单后,我的javascript会隐藏一个div并显示另一个:
function deviceReady() {
console.log("deviceReady");
$("#loginPage").on("pageinit",function() {
console.log("pageinit run");
$("#loginForm").on("submit",handleLogin);
checkPreAuth();
});
$.mobile.changePage("#loginTest");
$('#loginTest').html('Hello World!');
}
底线是我正在尝试向动态显示的div添加一些文本。但是,div中没有显示任何内容。我还想在同一个文件中显示另一个函数的变量。
这是下面代码中的var e = $("#username").val();
,我想最终添加到div中。
function init() {
document.addEventListener("deviceready", deviceReady, true);
delete init;
}
function checkPreAuth() {
console.log("checkPreAuth");
var form = $("#loginForm");
if(window.localStorage["username"] != undefined && window.localStorage["password"] != undefined) {
$("#username", form).val(window.localStorage["username"]);
$("#password", form).val(window.localStorage["password"]);
handleLogin();
}
}
function handleLogin() {
var e = $("#username").val();
var p = $("#password").val();
if(e != "" && p != "") {
$.ajax({
type: 'POST',
url: 'http://localhost/php/log.php',
crossDomain: true,
data: {username: e, password :p},
dataType: 'json',
async: false,
success: function (response){
if (response.success) {
$.mobile.changePage("#loginTest");
}
else {
alert("Your login failed");
}
},
error: function(error){
alert('Could not connect to the database' + error);
}
});
}
else {
alert("You must enter username and password");
}
return false;
}
function deviceReady() {
console.log("deviceReady");
$("#loginPage").on("pageinit",function() {
console.log("pageinit run");
$("#loginForm").on("submit",handleLogin);
checkPreAuth();
});
$.mobile.changePage("#loginTest");
$('#loginTest').html('Hello World!');
}
HTML代码:
<body>
<div id="loginPage" data-role="page">
<div data-role="header">
<h1>Auth Demo</h1>
</div>
<div data-role="fieldcontain" class="ui-hide-label">
<label for="username">Username:</label>
<input type="text" name="username" id="username" value="" placeholder="Username" />
</div>
<div data-role="fieldcontain" class="ui-hide-label">
<label for="password">Password:</label>
<input type="password" name="password" id="password" value="" placeholder="Password" />
</div>
<input type="button" value="Login" id="submitButton" onclick="handleLogin()">
<div data-role="footer">
</div>
</div>
<div id="loginTest" data-role="page">
<div id="name">
</div>
</div>
</body>

在元素id loginTest(#loginTest)
上尝试此操作document.getElementById('loginTest').innerHTML= your variable here; //or any string
如果您使用的是jquery
$( '#loginTest' ).text( your variable ); //or any string

你不能更好地限制帖子:
<input type="button" value="Login" id="submitButton" onClientClick="handleLogin()">
然后从函数返回false。
