how can call a html page div from javascript?
I am working on phonegap with android. I am creating a login page. After the login validation I want to jump to the welcome div if the user is authorized .
This is my javascript page:- myjavascrpt.js
var logi=item.id;
if(logi>0)
call welcome div of index.html
else
alert("invalid user");
// in this logi variable i have userid of successful user.
// now i want to
// display this id into the div which is exist in my
// html page.
// now what should i write here so i can call welcome
// div of html page and i can use
// this value of logi variable.
开发者_运维知识库This is my index.html whose welcome div I want to call.
<html>
<head></head>
<body>
<div data-role="page" data-theme="a" data-url="streaming" id="streaming">
<h1> do some thing related to streaming</h1>
</div>
**
<div data-role="page" data-theme="a" data-url="welcome" id="welcome">
<h1> you are welcome</h1>
</div>
**
</body>
</html>
so please tell me what code should I use to call the div of a html page.
I don't know anything about calling a html page div from javascript, but if you want to set the content of a DIV via javascript, it's done that way:
In javascript:
var d = document.getElementByID("welcome");
d.innerHTML = logi;
But this would override the <h1> you are welcome</h1> text. So change that line to be
<span id="userwelcome"></span><h1>, you are welcome</h1>
and your javascript to
var d = document.getElementByID("userwelcome");
d.innerHTML = logi;
You can do that with simple jQuery -
if(logi>0) { $('#welcome').html(logi);}
加载中,请稍侯......
