Menu
I made a little web-based web browser for a web-based OS I made. I noticed that in some sites, they have links that like to open in new tabs. Is there a way that this can be prevented and have the links open in the iframe instead?
Here's my code for the whole browser just in case:
<html>
<head>
<link href="./browser.css" rel="stylesheet" type="text/css"/>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script>
$(function() {
$("#load").click(function() {
var new_url = $("#url").val();
// Checks that the user typed "http://" or not
if(new_url.substr(0,7)!="http://")
new_url = "http://"+new_url;
$("#main_frame").attr("src", new_url);
});
});
</script>
</head>
<body>
<div id="help">
<form action="help.html"><input type="submit" value="Help"></form>
</div>
Address:
<div id="logo">
<img src="stallion.png">
</div>
<input type="text" style="width: 400px;" name="url" id="url">
<input type="button" value="Go" id="load">
<div>
<input type="image" src="back.png" height=25 width=25 onclick="back()">
<input type="image" src="forward.png" height=25 width=25 onclick="forward()">
<input type="image" src="refresh.png" height=26 width=26 onclick="refresh()">
</div>
<iframe frameborder=0 class="netframe" src="http://www.bing.com/" id="main_frame"></iframe>
</body>
<script>
function back()
{
window.history.back();
}
</script>
<script>
function forward()
{
window.history.forward();
}
</script>
<script>
function refresh()
{
var iframe = document.getElementById('main_frame');
iframe.src = iframe.src;
}
</script>
</html>

There is two choices
1 : You can check all of the html in the iframe on each change and look for "target=_blank" and if so replace with "target=_self"
2 : Which I think would be the better way is, when the user clicks on an anchor tag check to see if the anchor has the attribute "target=_blank" if they do, simply remove it and then click the link.
I have provided a jsFiddle below
https://jsfiddle.net/L5dhp80e/
Html
<a class="newTab" href="http://www.google.com" target="_blank">
New Tab Google
</a>
<br />
<a class="removeBlank" href="http://www.google.com" target="_blank">
Removed Target Blank Google
</a>
Javascript
$(function () {
$('a.removeBlank').on('click', function () {
if ($(this).attr('target') == "_blank") {
$(this).attr('target', '_self');
}
$(this).click();
return false;
})
});
However if the iframe content is cross domain I don't think you can edit any of the code at all.
