Having a data grid with a hyperlink control that allows users to open a new tab displaying selected item information poses the issue of multiple tabs opening when the same item is clicked multiple times. Is there a way to have the tab open only the first time the link is clicked, and if it's already open, redirect focus to the existing tab instead of creating a new one?
The hyperlink control is set to target "_blank".
This situation is being handled in C# and Asp.net 4.5.
To define a name in the target attribute, you can do the following:
<asp:HyperLink
NavigateUrl="https://www.google.com"
Text="Go to Google"
Target="SameWindow"
runat="server"/>
<asp:HyperLink
NavigateUrl="http://stackoverflow.com"
Text="Go to StackOverflow"
Target="SameWindow"
runat="server"/>
HTML example:
<a href="http://www.google.com" target="SameWindow">Go to Google</a>
<br />
<a href="http://stackoverflow.com" target="SameWindow">Go to StackOverflow</a>This method is similar to using the JavaScript window.open function to assign a name to a window. Once a named window is opened, subsequent calls to window.open with that name specified will load the new URL in the existing window.
Below is a example snippet. Please run this code in a full JSFiddle page due to security limitations (CORS).
var openTarget = function() {
console.log(this);
var target = this.getAttribute("attr-target");
window.open(target, "ExampleName");
}
var elems = document.querySelectorAll("button");
Array.prototype.forEach.call(elems, function(e) {
e.addEventListener("click", openTarget);
});<button attr-target="https://www.google.com/">Open Google</button>
<button attr-target="http://stackoverflow.com/">Open StackOverflow</button>To assign the target, simply specify a name to use
<a href="http://bing.com" target="newname">a hyperlink</a>
Learn how to achieve this using the following straightforward method:
<a href="www.example.com" target="_blank">Click Here</a>
