I have a php page which has lot's of code of html and javascript inside it.Ihe other page use ajax to send an id to the first page and get the results and put it inside a div element. Now I want to run those returned codes which contains javascript and html codes.
How should that be done?
This is my ajax request to the first page:
$(document).ready(function() {
$.ajax({
type: "POST",
url: "showing.php",
data: "s_id="+s_id+"&submit=true",
success: function(msg){
str=$.trim(msg)
document.getElementById('tabs-2').innerHTML = str;
document.getElementById("ui-id-2").click();
}
})
I think event delegation can solve your problem.
Like below:
Use $.on(). Instead of registering events on the element you register on a parent which will not be removed
Ex:
$('#tabs-2').on('click', '#ui-id-2', function(){
//do something
})

But it doesn't work, how to do it?
I want to know how to send ajax request in embeded javascript of pug file
To me there seems to be two issues
You have put unnecessary tabs in your function under (function (){
You need to use document.ready to ensure that HTML content is
ready. You can avoid this if you don't really care for DOM once you have the response
check a working example below
doctype html
html
head
script(src='https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js')
script.
$(document).ready(function(){
$.ajax({url: "demo_test.txt", success: function(result){
$("#div1").html(result);
}});
});
body
#div1
h2 Let jQuery AJAX Change This Text
Here there is no problem with your pug template (maybe just you can remove ()after #payment-form() because it is empty and it's not a mixin). But with your JS, you send the AJAX request immediatly, you should bind it to an event (click on a button, keypress on an input, etc.). Then you have to be sure you put your lib jquery.js in a directory you can access from your browser with scripts/jquery.js. If it's still not work after this change please report more precisely your error (open the console to get the messages, get us the behavior you expect and the behavior you get).
I have a php page which includes jQuery and a script.js file. When I put the following function inside my php file, the function gets executed and works as intended:
<script>
$('#scoreboard-overview').load('getusers.php?q=<?php echo $NewString; ?>').fadeIn("slow");
</script>
What does it do? Wel it reloads the div with id scoreboard-overview in my php file with data from an external php file called getusers.php
This all works great.
Now in the script.js file (which is loaded at the end of the php page, right before </body>), I also want to reload this div when the updatescore.php file is done updating the database via a form. I have this code for it:
$.ajax({
type: "POST",
data: $("#form").serialize(),
cache: false,
url: "updatescore.php",
success: function() { //reload overview
$('#scoreboard-overview').load('getusers.php?q=' + document.getElementById('str') + '').fadeIn("slow");
}
});
So after success it should execute the jQuery function:
function () { //reload overview
$('#scoreboard-overview').load('getusers.php?q='+document.getElementById('str')+'').fadeIn("slow");
}
I verified the code. The database gets updated using updatescore.php but after this (so after success), the div isn't refreshed. So this success part of code isn't working. What am I doing wrong?
ps: '+document.getElementById('str')+' should give me the same result as echo $NewString; only taken from the div with id str (since php doesn't work inside a js file?)
document.getElementById('str') is going to return the HTML element with the 'str' id, not the text within the element. I'm not sure what this element actually looks like, but you might do something like document.getElementById('str').textContent.
The question might be a little misleading as I don't want to know how to open a html document in a div ,but I asked the question as I am currently facing a problem where I can't replace the html file which I have already placed in a div
I have already placed a html file in a div using ajax like this:
$.ajax({
url: 'calender.aspx',//this is html.aspx file
cache: false,
dataType: "html",
success: function (data) {
$(".mainBar").html(data);//mainBar is the div
}
});
this file gets placed on page load i.e document.ready function ,till here everything is fine.....my trouble starts when I want to replace the file,what I do is call a javascript function say replaceFile() on button click and write the same code to replace the file (changing the url of course)
like this
function replaceFile()
{
$.ajax({
url: 'Another.aspx',
cache: false,
dataType: "html",
success: function (data) {
$(".mainBar").html(data);
}
});
}
but this doesn't work,please help me out!
I guess your binding is not working when you try to click on the content you loaded via ajax . So you might want to change the binding of onclick from
$("#someButtonId").click(function(){
replaceFile();
});
to
$(document).on("click","#someButtonId",function(){
replaceFile();
});
jQuery on works with current and future elements.
with this function you will load the page into the element named result
.load( url , data, complete(responseText, textStatus, XMLHttpRequest)] )
function replaceFile(url)
{
$('#result').load(url, function() {
alert('Load was performed.');
});
}
replaceFile('htmlfile.html');
You can load this in Firebug and set a break point at $(".mainBar").html(data); to make sure it's being called. You don't have a failure handler, so it's possible that it's actually receiving an HTTP failure code, not a success code.
I'd also look at the network traffic under the Net tab to see what the request/response looks like. That's an easy way to find out what is really going on with most AJAX calls. IE9 has similar developer tools if you want to use it and not Firefox or Chrome.
I have a json implemented page where I am displaying a list of videos. I am getting the video <embed> codes as a javascript. While in the loop of creating the list, I use the $.ajax jquery function to initialize the javascript to get teh video flash player. but the problem is that the player is not getting appended to the supposed <div>. Instead it gets appended at teh end of the document.
$.ajax({
url: item.ImagePath,
dataType: "script",
success: function(data){
alert(data);
var sResultFigure = $(document.createElement('figure')).append(result);
}
})
how do i solve this thing?
Well, you have to append it to the supposed div, like this:
var sResultFigure = $('<figure></figure>').append(result);
$('#supposedDiv').append(sResultFigure);
Assuming you are looping over divs and triggering an AJAX request for each div you could use the context parameter of the AJAX call to provide the current div to the success handler:
$('div.foo').each(function(index, div) {
$.ajax({
url: item.ImagePath,
dataType: 'script',
context: div,
success: function(data) {
// here $(this) points to the div over which we were looping
// when we triggered the AJAX request
$(this).append($('<figure/>').append(result));
}
});
});
i assume your div's id is "holder".
var sResultFigure = $("<figure></figure>").append(result);
$('#holder').append(sResultFigure);
I want to make a few divs on the same page work similar to iframes. Each will load a URL which contains links. When you click on those links I want an AJAX request to go out and replace the div's html with new html from the page of the clicked link. It will be very similar to surfing a page inside an iframe.
Here is my code to initially load the divs (this code works):
onload:
$.ajax({
url: "http://www.foo.com/videos.php",
cache: false,
success: function(html){
$("#HowToVideos").replaceWith(html);
}
});
$.ajax({
url: "http://www.foo.com/projects.php",
cache: false,
success: function(html){
$("#HowToProjects").replaceWith(html);
}
});
This is a sample of code that I'm not quite sure how to implement but explains the concept. Could I get some help with some selectors(surround in ?'s) and or let me know what is the correct way of doing this? I also want to display a loading icon, which I need to know where the right place to place the function is.
$(".ajaxarea a").click(function(){
var linksURL = this.href; //
var ParentingAjaxArea = $(this).closest(".ajaxarea");;
$.ajax({
url: linksURL,
cache: false,
success: function(html){
$(ParentingAjaxArea).replaceWith(html);
}
});
return false;
});
$(".ajaxarea").ajaxStart(function(){
// show loading icon
});
Assuming you want to listen to click events for all anchor tags inside all elements with class ajaxarea, then your selector works fine:
$(".ajaxarea a").click(function(){ .. });
And this line of code, while not a selector (you're just accessing a property on the DOM element that was clicked), should work fine as well:
var linksUrl = this.href;
As for ParentingAjaxArea, you'll need to use $(this).closest() with a selector to determine which parent you want, but it's hard to give a specific example without knowing your HTML structure. It looks like you want ParentingAjaxArea to be either the element with id #HowToProjects or #HowToVideos, so you could write:
var ParentingAjaxArea = $(this).closest("#HowToProjects, #HowToVideos");
As for the loading dialog, I think this answer explains a good method (using ajaxStart and ajaxStop).
Edit: I also noticed you're using the click event--If you plan on being able to attach event handlers to links that will be inserted into the DOM via AJAX later, look at delegate or live.
$(".ajaxarea a").live('click',function(e){
e.preventDefault(); //*
var URL = $(this).attr('href');
var parentFrame = $(this).parent(".ajaxarea"); //**
$.ajax({
url: URL,
cache: false,
success: function(html){
parentFrame.replaceWith(html); //***
}
});
});
* - added preventDefault to prevent click action (see e in function's arguments)
** - instead of closest, i used parent – like it more for it's descriptive qualities
*** - the var containing parent AJAX frame should be jQuery object, no need to wrap it in $(..)
This should work fine, but beware, it's untested.
edit:
You probably need a live (okay, I'm sure you need it). what click() does it's that it adds to all elements at the time in DOM an onClick event. What live() does, it's that it waits for any change in DOM and runs used selector (.ajaxarea a) again and if it fits for any of new elements, it adds the action. In pseudocode, it does basically this:
DOM.hasChanged{
$('selector').click(..)
}
I used this example for my own web page:
http://www.queness.com/post/328/a-simple-ajax-driven-website-with-jqueryphp
It works quite well and uses hash tags and jQuery.history.js for the history of your browser. It works very nice, because you can let something like a media player just continue playing. Take a look at my own site elsewise, where you can find the javascript file: ajaxpages.js. I haven't used live(), but maybe I should.
Figured it out! The problem was I was using the function ".replacewith()" which was removing my AJAXed div(class="ajaxarea") entirely instead of replacing the content. The proper function to use here was ".html()".
Here is my working code to make an AJAXed div work like an iframe:
//onload to initialize the div
$.ajax({
url: "http://www.foo.com/projects.php",
cache: false,
success: function(html){
$('#HowToProjects').html(html);
}
});
$(".ajaxarea a").live('click',function(e){ // must use live instead of .click()
e.preventDefault();
var URL = $(this).attr('href');
var parentFrame = $(this).closest(".ajaxarea");
$.ajax({
url: URL,
cache: false,
success: function(html){
parentFrame.html(html);
}
});
});
