jQuery Ajax Render Fragments OR Whole Page -
i'm in throes of building application wraps mess of legacy code. page working on, need substitute fragment divs constructed on back-end -- or else need replace entire page altogether. idea there dynamically controlled flow needs satisfied before can forward legacy product.
substituting fragments works fine, seen in below my_body_content swap. trouble comes when i'm trying render not fragment, whole page, in "body" swap. @ point page goes blank.
i want similar errors returned server. want nice rest 404 error messages displayed on screen, legacy-product 404s show in legacy-product 404 page.
yes, requirements project weird. that's not problem can fix.
here's jquery invocation, names changed protect guilty:
$.ajax({ url: "places/things", type: "post", data: json.stringify(somebadassobject), datatype: "text", accepts: "text/html", contenttype: "application/json; charset=utf-8", success: function(x) { var fragcheck = $("#my_fragment", x); if (fragcheck != null && fragcheck.length > 0) $("#my_body_content").html(x); else $("body").html(x); }, error: function (xmlhttprequest, textstatus, errorthrown) { error(errorthrown); if (xmlhttprequest.responsetext.startswith("<html>")) $("body").html(xmlhttprequest.responsetext); } });
okay, think can answer own question:
$("body").html(x); doesn't work, and
$("html").replacewith(x); doesn't work, , other permutations along same idea don't work either.
this works:
document.open(); document.write(xmlhttprequest.responsetext); document.close(); so whole solution looks this:
$.ajax({ url: "places/things", type: "post", data: json.stringify(somebadassobject), datatype: "text", accepts: "text/html", contenttype: "application/json; charset=utf-8", success: function(x) { var fragcheck = $("#my_fragment", x); if (fragcheck != null && fragcheck.length > 0) $("#my_body_content").html(x); else { document.open(); document.write(x); document.close(); } }, error: function (xmlhttprequest, textstatus, errorthrown) { error(errorthrown); if (xmlhttprequest.responsetext.startswith("<html>")) { document.open(); document.write(xmlhttprequest.responsetext); document.close(); } } });
hope helps next poor schmoe!
Thanks for suggesting hiring via outsourced experts. I also preferred the same thing a month ago. I hired some java spring framework experts through an amazing platform named Eiliana.com. Now, I am very happy with the work of those employed, and I recommend the same to my fellow business owners. They are actively looking to hire professional experts in technical niches.
