我将数据存储在本地存储中。但是当我试图从本地存储中检索数据时,输入标签中没有数据。当页面发生变化时,它应该会到来。请帮帮我。代码中的错误是什么?
在 HTML5 中:
<div data-role="page" id="page1">
<div data-role="content">
<form novalidate id="setting_form">
<div data-role="fieldcontain">
<label for="textusername1">Username</label>
<input name="textusername1" id="textusername1" value="" type="text">
</div>
<div data-role="fieldcontain">
<label for="textpassword1">Password</label>
<input name="textpassword1" id="textpassword1" value="" type="text">
</div>
<div style="text-align:center;">
<div data-role="button" data-theme="b" data-inline="true" id="button1" onclick="callConnection();">Update</div>
</div>
</form>
</div>
</div>
<div data-rol2="page" id="show">
<div data-role="content" id="content2">
<form novalidate id="setting_form1">
<label for="un">User Name</label>
<input type="text" name="un" class="field" id="un" value="">
<label for="pw">Password</label>
<input type="text" name="pw" class="field" id="pw" value="">
</div>
</div>
在 jQuery 中:
$(document).unbind('pageinit').bind('pageinit', function () {
$("#show").on("pageshow", function (event) {
$("#un").text(localStorage.getItem("user"));
$("#pw").text(localStorage.getItem("pass"));
});
});
function callConnection(){
localStorage.setItem("user", $("#textusername1").val());
localStorage.setItem("pass", $("#textpassword1").val());
if (localStorage.getItem("user") == "" && localStorage.getItem("pass") == "") {
alert("enter the username and password");
}
else {
$.mobile.changePage("#show");
}
}
