I have a button call this script, so it does the post in the background, but I need to reload the current page to display an updated php query, I realize there was probably a better way in jquery to the query part, but its crunch time, and all I want to do is get a successful page refresh.
Because the buttons were generated in php, the javascript code is at the end of the body.
I've tried location.href, window.location.reload(true);, document.write which only wrote to the page, document.location.href did nothing.
We are using jQuery/jQuery mobile, I was not on front end dev team, so I'm desperate to get this to work. to clarify, I need a page refresh after the $.post() command, within this code, which does work
<script type="text/javascript">
$('#reserveBook').click(function () {
var isbn = sessionStorage.getItem('isbn');
$.post(
"../inventory/postpage.php",
{ isbn: isbn }
);
});
</script>
There's no point in using AJAX if you need a page refresh regardless. As Dan Bracuk said in his comment, you'd be better off just doing a traditional form submission.
However, if you're set on having the page refresh, just add window.location.reload() in the success handler for your AJAX call:
$.post(
"../inventory/postpage.php",
{ isbn: isbn },
function(response) {
window.location.reload();
}
);

So i am building a search on website, and main search form is on home page where user can input information's like, interests, books, movies.
And that form should submit to another page where search will be displayed.
So it's similar like any other search, but on search page, i should keep parameters in url, so it's not going to be POST, it would be GET.
Home page is something like mywebsite.com
And when form is submitted it's posted with GET parameters so user can keep search results in his url. Submitted post should lead to something like.
mywebsite.com/search?interests=sports&books=harry+potter&movies=moviename
And because it can take some time to search and load results i would like to load the page and than do an ajax post to search function and populate search results once ajax responds.
I've built in past some ajax content loading and post and load data with ajax, but all that while keeping on same page, i never built when you submit content from one page to another in wordpress.
Any suggestions how can i do that and make ajax grab the content ?
I found the answer, and it's actually quite easy, instead triggering ajax with function, for example function with button click.
Just trigger ajax on page load, and don't enqueue script anywhere else except on that page, this would help a bit.
if ( is_page_template('template-search.php') ) {
wp_enqueue_script('ajax_search');
}
This will ensure script is loaded only on that template page, and as for script it self, just load ajax on page ready:
jQuery(document).ready(function($) {
jQuery.ajax({
dataType: 'json',
url: search_flight.ajaxurl,
data: {
action: 'search_flight',
},
beforeSend: function() {
},
success: function(data) {
console.log(data);
},
error: function() {
}
});
});
I have a login screen which the user logs in using Jquery and AJAX. That's fine. Now what I want is that if the user logs in correctly, I want to load another page.
I tried using document.location = "home.html"; but that refreshes my page. What I want is like that transition that normally we have when we click on tag like
<a href="SchoolMaterials.html"> <!-- this does not refresh -->
I don't know if I explained myself clearly.
Thanks
It will be better to load the page in your callback function of successful login with:
$("#the_div_container_for_new_page").load("SchoolMaterials.html")
UPDATED:
it is something like this:
$(document).ready() {
function login() {
//post with ajax to login
$.post(......, function(result){
if (result.success) {
// load some page after successful login.
$('#id_of_container_div').load("thepage.html");
return;
} else {
// handle error
}
})
}
}
window.location is just what you need. You can also create an anchor element using jQuery and simulate a click on it :
$("<a href='your url'></a>").click();
But i wouldn't recommend that, it's better to post your data to the server and redirect to the page you want.
I'm currently in the midst of creating a generator which echoes a random line from a .txt file. All is well and good however I need to have this certain part of the page which echoes the random line refresh when a button is clicked. I've tried multiple methods to no avail and I'm running out of ideas - I'm still quite new to JavaScript/AJAX and have no idea on how to go about it. Any help would be brilliant, thanks!
Use Jquery Ajax to get contents from the file and display the contents into a div
$.ajax({
type: "GET",
url: "yourfilename.txt"
}).done(function( msg ) {
$("#YOURDIVID").html(msg.d);
});
Bind click event of your button
$(function(){
$("#YOURBUTTONID").on("click",function(){
//do your work
});
});
Refreshing logic can be wrapped into a function and called on click of button OR you can use javascript settimeout method.
I have a code that after clicking on a link ('#versionPageFromProdLink'), will redirect the page to the index page. The index page has that contains the content. I want to hide this after the page is redirected and show the next div that i have ().
The page is redirected however the jQuery function after the window.location.replace( url ); line is not called.
How will I be able to redirect and call the jQuery after page redirection?
Code:
jQuery( '#versionPageFrmProdLink').click( function(){
window.location.replace( url );
// jQuery code below is not called, <div id="versionMainContent"> is not hidden
jQuery(".versionMainContent").hide("fast", function(){
jQuery( ".versionProductContent" ).show();
});
});
As stated, the location.replace means the code "after" it won't execute. What you will need to do, is append a hash "index.html#divCode" or some such (you could also use a query string in this case) and then detect that onload / on document-ready for the index page, then update the hide/show status there.
This is fundamentally impossible.
Once you navigate to a different page, the previous page, including all of its Javascript, is gone.
You must handle the secondary executation after the redirect in the page you are redirecting to.
Example:
Page 1
jQuery( '#versionPageFrmProdLink').click( function(){
window.location.replace( url );
}
Note during redirection you can pass a query string in the URL to check a condition in the next page.
Page 2
Now that you redirected to the next page. You can place a document.ready function and run what is needed.
$(document).ready(function () {
jQuery(".versionMainContent").hide("fast", function(){
jQuery( ".versionProductContent" ).show();
});
Your design is the problem. Redirecting stops the flow of execution. You can use ajax to make a server call and continue execution.
Or, if you prefer you can perform a redirect and pass a URL parameter like ?hideVersionMainContent=true and perform the hide server side.
There are other ways to accomplish the task, but that should give you a few ideas.
The code after your location.replace operates on the page that you're leaving (if it is ever run at all; changing the location navigates away from the page and may well terminate your code right there).
You'll need to pass the information to display to the new page, and have code on the new page fill in the stats. There are lots of ways to do that:
On the query string
Via web storage (sessionStorage would probably make sense)
Cookies (but don't, it's not what they're for)
I have a search script written in jQuery. To submit a query a user presses enter and then a URL for the results page is created which is something like #search/QUERY/. However, when you either reload the page, click a result which goes to a different page or return back from a previous page the search results are no longer there. Why could this be?
My jQuery code is:
$(document).ready(function(){
$("#search").keyup(function(e){
if(e.keyCode==13){
var search=$(this).val();
var query=encodeURIComponent(search);
var yt_url='search.php?q='+query;
window.location.hash='search/'+query+'/';
document.title=$(this).val()+" - My Search Script";
$.ajax({
type:"GET",
url:yt_url,
dataType:"html",
success:function(response){
$("#result").html(response);
}
});
}
});
});
When a user reloads the javascript, all variables and functions are reinitialized. JavaScript does not pass variables from page to page. You either need a server side solution, or use JavaScript storage. The later may not work in all browsers.
This is because you are loading the search results dynamically with an AJAX call. If the page gets reloaded, that information gets lost.
A possible solution would be to store the search query and/or results in the user session. Then you will be able to automatically add the content on page reloads.
