I want to create a Javascript file to do these operations:
- Pass the current link to the other page
- Click on hypertext or image that is created dynamically in JavaScript file to redirect
Just I want to have a Javascript link in the html body and not other thing same this :
<div>
<script type="text/开发者_如何学JAVAjavascript" src="JScript.js"></script>
</div>
And in the JavaScript file I have these:
var DivTag = document.createElement("Div");
DivTag.setAttribute('ID', 'MyDivTagID');
$(document).ready(function () {
$("$MyDivTagID").click(function(e) {
window.location = "http://www.MyLink.com/?Url=" + window.location;
});
});
This is not working. Please help me.
Several issues
- you never added the div to the page
- you used $ instead of # to access the div by ID
- you do not consistently use jQuery
Plain JS: DEMO HERE
window.onload=function () {
var DivTag = document.createElement("div");
DivTag.setAttribute('id', 'MyDivTagID');
DivTag.innerHTML="Click";
DivTag.onclick = function(e) {
window.location = "http://www.MyLink.com/?Url=" + escape(window.location.href);
}
document.body.appendChild(DivTag);
}
Using linked image:
window.onload=function () {
var DivTag = document.createElement("div");
DivTag.setAttribute('id', 'MyDivTagID');
var anchor = document.createElement("a");
anchor.href="#";
anchor.onclick = function(e) {
window.location = "http://www.MyLink.com/?Url=" + escape(window.location.href);
}
var img = document.createElement("img");
img.src="image.gif";
img.style.border="0";
anchor.appendChild(img);
DivTag.appendChild(anchor);
document.body.appendChild(DivTag);
}
jQuery: DEMO HERE
$(document).ready(function () {
$('body').append('<div id="MyDivTagID">Click</div>');
$("#MyDivTagID").click(function(e) {
window.location = "http://www.MyLink.com/?Url=" + escape(window.location.href);
});
});
A small change to the jQuery code from mplungjan:
Change:
$(document).ready(function () {
$('body').append('<div id="MyDivTagID">Click</div>').click(function(e) {
window.location = "http://www.MyLink.com/?Url=" + escape(window.location.href);
});
});
To:
$(document).ready(function () {
$('body').append('<div id="MyDivTagID">Click</div>').find('#MyDivTagID').click(function(e) {
window.location = "http://www.MyLink.com/?Url=" + escape(window.location.href);
});
});
If you output e.currentTarget
from the anonymous click handler function you get body
since the event handler was attached to the body
in mplungjan's solution. All I did was add .find('#MyDivTagID')
directly after the .append()
function so the click handler gets attached to the div
and not the body
.
