Is there a way to preselect an option on another page before it loads?
Consider two pages, A and B.
If a user clicks a button on page A, I want the default option on page B to be changed to "something" before redirecting them. How can this be achieved so that the change occurs before page B is loaded?
If you want to go the route of using only JavaScript and HTML without any backend language, one approach is to utilize a GET Variable.
HTML for Page 1:
<a href="p2.html?v=1">Option 1</a><br />
<a href="p2.html?v=2">Option 2</a><br />
HTML for Page 2:
<form>
<input id="Option1" type="radio" name="Option" value="1">Option 1 </input>
<input id="Option2" type="radio" name="Option" value="2">Option 2 </input>
</form>
Javascript for Page 2:
var queryDict = {}
location.search.substr(1).split("&").forEach(function(item) {queryDict[item.split("=")[0]] = item.split("=")[1]}) //Parse GET Params
document.getElementById("Option" + queryDict["v"]).checked = true; //Set Option checked
If you're looking to store values between two pages in a user's browser, one option is to utilize JavaScript's localStorage() object. For example, on page A, you could implement the following:
$(document).ready(function(){
$('a.PageALink').click(function(){
localStorage.setItem("PageAValue", $(this).text()); // Alternatively, you can use data attributes for storing values differently
});
Then, on Page B:
$(document).ready(function(){
$('a.PageBLink').text(localStorage.PageAValue);
});
This solution relies on jQuery, so make sure it is either already included on your page or that you are comfortable adding it. If using jQuery is not an option for you, feel free to specify any constraints you have regarding dependencies and scripting.
