load php page from jquery ajax post unloading the current page - javascript

I need to generate a report showing in a php page which will be called by a jquery ajax call. Can any body help me on how to do this.
The jquery ajax post is as following:
$('#report_condition #Submit_rpt_betn_dates').on('click', function(){
var start_dt = $('#report_condition').find('.rpt_betn_dates').find('.start_search_date').val();
var end_dt = $('#report_condition').find('.rpt_betn_dates').find('.end_search_date').val();
alert('you want to generate report between '+start_dt+' and '+end_dt);
$.ajax({
type: "POST",
url: "./report-betn-dates.php",
data: {'startdt':start_dt, 'enddt':end_dt}, //the first parameter in the pair is actually the key for $_POST in PHP
//and it must be withing quotes for ajax to run!!
crossdomain: true,
success: function(response) {
}
});
});
I tried with $('body').html(response); within success parameter of the ajax call. But by this I cannot access the separate css file for the php page. Hence I would like to unload the page containing the ajax call and load the php page with the data sent through $_POST[].

Ajax is for partial content load, asyncronous interactions , etc.. Since what you're trying to achieve is complete new page loaded with its own static resources (css, js) this is the perfect "syncronous" scenario.
So, why wouldn't you use a simpler setup like a form which sends the required vars in post and moves the user to the correct php page?
$('#report_condition #Submit_rpt_betn_dates').on('click', function(){
var fake_form = $('<form method="post" action="report-betn-dates.php">');
var input_start = $('<input type="hidden" name="startdt">');
var input_end = $('<input type="hidden" name="enddt">');
$(fake_form).append(input_start);
$(fake_form).append(input_end):
$(fake_form).submit();
});

Return variable from PHP after AJAX Post

I've read countless examples but I just can't get the following to work. I want to submit a form, process it on the server side then decide which php script to load into a div (dynamic loading I can do).
The head:
$.ajax({
type: "POST",
url: url, // passed with onclick
data: $("#" + formName).serialize(),
success: function(data) {
// Some JSON? to go here to store variable returned from PHP ($thisVariable)
}
});
return false; // avoid to execute the actual submit of the form.
The php:
// Process the request (add to database e.g.)
$thisVariable back to ajax

jQuery onClick pass a variable via GET to URL and load that URL

I know how to pass variables through AJAX calls via onClick to a PHP file and asynchronously loading the results on the initial page.
I now need to analogously pass a variable via onClick to a PHP file but I need to open a new window or redirect the whole page with the passed variable. The URL needs to contain the variable, so that the query/results can be "statically" sent to someone, like 'xyz.php?var=xyz'
I thought I could do something like this
$("#submit").click(function(event) {
var category_id = {};
category_id['linkgen'] = $("#linkgen").val();
$.ajax({
type: "GET",
url: "generatedlink.php",
dataType: "html",
data: category_id,
success: function(response){
window.open('generatedlink.php');
}
});
});
This only opens 'generatedlink.php'. I actually want what is passed via AJAX, i.e. 'generatedlink.php?linkgen=blabla' onClick in a new window/reloaded page! I'd very much appreciate your help.
just try: without ajax call
$("#submit").click(function(event) {
window.open('generatedlink.php?inkgen='+$("#linkgen").val());
});

How do I reload a page without the user noticing?

I've been trying to figure out how to reload a page and pull dynamic info from a server without users noticing the page has been reloaded. For instance, if I want to create a 'live' message board system when the board updates every time other people make a comment or post a message.
I noticed that Javascript has a boolean function .reload() that when set to false reloads the page from the cache and when set to true reloads the page from the server, but from what it looks like, the function does something similar to reloading the browser. Is there another way do what I'm trying to do?
Something like this...
function getContent()
{
return new Promise(function(resolve, reject){
var url = "http://yourendpoint.ext"
$.ajax({
url: url,
success: function(data)
{
resolve(data);
},
error: function(err)
{
reject(err);
}
});
}));
}
// Usage
getContent()
.then(function(data)
{
$('#some-element').html(data);
});
Are you sure you really want to do an reload?
What you could do is make an AJAX Request to the server and display the result, without even reloading the Page. I would recommend using jQuery for this, just out of comfort.
AJAX stands for Asynchronous JavaScript and XML. In a simple way the process could be:
User displays page, a timer is started
Every 10s (or 20s or whatever) you do an AJAX Request using JavaScript, asking the server for new data. You can set a callback function that handles the result data.
Server answers with result data, your callback function inserts the new data.
Code Example (taken from jQuery Docs):
$.ajax({
method: "POST",
url: "target.php",
// Data to be sent to the server
data: { name: "John", location: "Boston" },
// success will be called if the request was successfull
success: function( result ) {
// Loop through each Element
$.each(result.newElements, function(index, value) {
// Insert the Element to your page
$('.classOfYourList').append(value);
}
});
});
Just set the proper endpoint of your server as the target and insert whatever you want to do in the success function. The function will get an answer containing whatever you sent to it from the server. More Information in the jQuery Documentation:
You can Achive what you want using AJAX. you can use ajax with either javascript or jquery. You can load the content you want dynamically without reloading the entire page. here is a quick example.
Here is a <div> with id load where your content will be loaded.
<div id="load">Loaded Content:</div>
<button id="load_more">load more</button>
JQuery to request for the data, where getdata.php is the php file which will send data you want to display.
<script type="text/javascript">
$(document).ready(function(){
$("#load_more").click(function (){
$.post("getdata.php", {variable1:yourvariable, variable2:ifneeded},function(data){
//data is the string or obj or array echoed from getdata.php file
$('#load').append(data); //putting the data into the loaded div.
}
});
});
});
</script>`
finally getdata.php file
<?php
//fetch data from Databas eif needed. or echo ut what you want to display in the div.
echo "This is a small example of using JQuery AJAX post request with PHP.";
?>
Hope that helps!

Send content created by javascript in PHP mail?

I'm using a javascript shopping cart on a store, and I want to send an order confirmation on checkout. The problem is that the cart isn't saved in database of any kind, and is printed with javascript. How would I attach it to the email? I've included the shopping cart script on the page that sends the mail.
<table class="simpleCart_items"></table> would print the cart, but how would I attach the printed cart to email?
Hidden input or something?
UPDATE
My ajax call looks like this:
var data = $('#yhteystiedot').serialize();
data.cartContent = $('.simpleCart_items').html();
//alert (dataString);return false;
$.ajax({
type: "POST",
url: "order.php",
data: data,
dataType: "text",
error: function(){ alert("Jotakin meni pahasti pieleen! Yritä uudelleen?");
},
success: function() {
$(document).html("Tilaus lähti.");
}
});
You can make an ajax call to a php function that sends an email. The argument is the content generated by javascript.
You'll need to post the cart values to serverside PHP script and recreate the HTML for the cart in order to be able to send it through email. You can do direct form post or ajax post based on your need.
I asume your $.ajax() call looks something like this:
$('form').submit(function(){
var dataTrunk = $(this).serializeArray();
dataTrunk.push( { name: 'cartContent', value: $(your_table_selector).html()});
$.ajax({
url: 'mail.php', // your mail script
data: dataTrunk,
type: 'post'
});
return false;
});
In php you would trap $_POST['cartContent'] and render it in email and send it.
If you are sending email with html and plain text body, then it would probably be a good idea to strip html elements and replace them with chars that are compatible with plain text.

Trying to open data retrieved from ajax to automatically download

Right now, I have a webapp that uses the jquery ajax to make a call (with params that change from call to call via a form) to my backend and retrieve an xml file. I want to put the xml data into a file with a different extension for a private application.
Basically I just want the user to be able to click a button, and it automatically prompts them to "open or save" a file containing the returned ajax xml data.
I've dabbled with sending a raw http header using php, but I can't figure out how to get it to work.
I'm writing all of this in javascript and jquery.
The only thing the below code does is (1)Make the Ajax Call, (2)Write the XML into an HTML page, (3) open the HTML page.
var format = function() {
$("button#format").click(function() {
$("#form").submit();
$.ajax({
url: "find",
beforeSend: function (xml) {
xml.overrideMimeType("application/octet-stream; charset=x-user-defined");
},
data: $("form#form").serialize(),
dataType: "html",
success: function(xml) {
xmlWindow = window.open("download.ivml");
xmlWindow.document.write(xml);
xmlWindow.focus();
},
error: function(request) {
$("#webdiv").html(request.responseText);
}
});
});
};
There is no need to force something like this into the AJAX paradigm, unless you need to play around with the data you retrieve before making it available for the user, then again, that should be able to be done in php. So I would do something like this:
<form id="format" action="download.ivml" target="_blank">
...
</form>
And in jquery modify the action like this
​$('#format')​.submit(function(){
// tweaking the post data, otherwise this whole block is not needed.
return true;
})​;
Finally on my server use a .htaccess file to handle that weird URL download.ivml
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^(.*)download.ivml$ /path/to/where/I/process/the/request
not quite sure about the syntaxis of this last .htaccess file though.
