JQuery not updating CSS elements after PHP include

I am loading PHP files with JQuery/Ajax.
This is the index.php file where the webpages are called
<div class = "view-screen">
<?php include('home.php'); ?>
</div>
Depending on which nav link is clicked, that page will display without refreshing.
$(document).ready(function() {
// ...
$navLinks.click( function() {
var $this = $(this)
target = $this.data('target')
toggleMenu()
$viewScreen.load(target + ".php")
$this.data('clicked', true)
if ($this.data('clicked') && target === "about") {
activateAbout()
}
return false
})
function activateAbout() {
console.log('activated')
}
}
The console log works, and displays 'activated'. The pages do load.
All of my scripts compile and link correctly to each other.
However, when I include code that updates the target page CSS in the activateAbout() function, it doesn't work. For example:
$('body').css("background-color", "white")
in activateAbout() works, but calling/updating CSS elements in the chosen .php file doesn't, such as
$('.about p').css("color", "white")
// OR
$('.about').toggleClass('activate')
I have a feeling this has something to do with the order in which these files are loaded, but I'm not sure! Thanks for the help in advance

This is common phenomenon. The reason you are not able to apply the css is because, your content is loading after, you call activateAbout(). I would recommend to call activateAbout() once the $viewScreen.load(target + ".php") loads the data successfully. jQuery.load() supports callback too. Refer to the example usage at https://www.w3schools.com/jquery/jquery_ajax_load.asp. So, it should look like
$(document).ready(function() {
$navLinks.click( function(){
var $this = $(this);
target = $this.data('target');
toggleMenu();
$viewScreen.load(target + ".php", function() {
$this.data('clicked', true);
if ($this.data('clicked') && target === "about") {
activateAbout();
}
});
return false;
});
});
function activateAbout() {
console.log('activated')
}
Also there is a trick using setTimeout which you can execute after certain time, when the view is expected to be loaded like below
if ($this.data('clicked') && target === "about") {
//The timeout period you can change accordingly
setTimeout(activateAbout, 300);
}
The recommended way is first type solution. Hope this helps you!!

Conditional fields based on select value in SiteOrigin Page Builder

I'm trying to integrate Page Builder by SiteOrigin into my plugin. I've added some custom fields under the row styles via the siteorigin_panels_row_style_fieldsfilter found here. One of the custom fields is a select. I would like fields to either be hidden or displayed when the select is at a certain value. I've enqueued the Javascript to Page Builder using the siteorigin_panel_enqueue_admin_scriptsaction as per the documentation, and have even added the panelsopen event with some test code:
jQuery( document ).ready(function($) {
$(document).on('panelsopen', function(e) {
$('select[name="style[test_field]"]').bind('change', function (e) {
if( $(this).val() == 'option1' ) {
$('input[name="style[second_field]').hide(500);
$('input[name="style[third_field]').show(500);
} else {
$('input[name="style[second_field]').show(500);
$('input[name="style[third_field]').hide(500);
}
});
});
});
However, this does not seem to be working. Any help or ideas how I could solve this would be greatly appreciated!

After some research I figured this out by using the ajaxComplete() function in jQuery. This is how it works:
$(function() {
$(document).ajaxComplete(function() {
$('select[name="style[test_field]"]').bind('change', function (e) {
if( $(this).val() == 'option1' ) {
$('input[name="style[second_field]').hide(500);
$('input[name="style[third_field]').show(500);
} else {
$('input[name="style[second_field]').show(500);
$('input[name="style[third_field]').hide(500);
}
});
});
});
I hope this helps anyone trying to achieve something similar.

excluding a page from javascript

I have a swipe to do back script for my ios web app that I have running across every page but what I want to know how is to exclude from affecting the first page that shows up. The script is this
<script>
$(document).bind('swiperight', function () {
history.back();
});</script>
How would exclude a page that has a hypothetical id of "home"?

I'm assuming you're using jQuery mobile (Apologies if you're not), you could use $.mobile.activePage to check if you're at home:
http://jquerymobile.com/demos/1.2.0/docs/api/methods.html (At the bottom)
<script>
$(document).bind('swiperight', function () {
if ( $.mobile.activePage !== 'home' )
history.back();
});
</script>

The general principle would be this:
<script>
var id = // get your hypothetical id from somewhere;
if(id !== "home") {
$(document).bind('swiperight', function () {
history.back();
});
}
</script>
Without any more information on where the hypothetical id is coming from it's difficult to be more specific than that.

$(document).bind('swiperight', function () {
if (!$('body#home').length === 0) {
history.back();
// ... anything else
}
});
You could also use: if (!$('#page.home').length === 0) if it's going to be a class on a containing element, if ($('#page').hasClass('home')) is a bit more of solid jQuery-y way of doing it too.

Using jquery to see if selector pulled any divs, find a div thats specific to example page

I'm pretty new to jquery, this is what i need help with: Using jquery to see if a selector pulled any divs, find a div thats specific to example page. See if first condition is false and if so redirect to example page. Thanks for any help!
Jquery partial code: "
$('.assessment-start').click(function () {
$('#startAssessmentDialog').empty();
//block
$('#startAssessmentDialog').block(_blockUISettings);
//block
var link = $('#startAssessmentDialog').attr('link');
AjaxUtil.Services.PageProxy.SendData(link, GLOBAL._HTTPVerbs.GET, {},
function (data) {
var $data = $(data);
$('#startAssessmentDialog').html($data.find('#surveyContainer'));
$('div[name*="*"]').val('*');</script>
// hide the unmapped capability areas
$("#unmappedCapabilityAreas").hide();
// unblocking
$('#startAssessmentDialog').unblock();
// unblocking
},
function (exception) {
AjaxUtil.DefaultExceptionHandler(exception);
$('#startAssessmentDialog').unblock();
}
);
"
Html code:
<div link="/Survey/details/#Global.CGSs[Model.CGSVersionID.Value].SelfAssessmentSurveyResourceID/#Model.ResourceID" id="startAssessmentDialog" class="noDisplay">
</div>

Seeing if selector got any divs:
var selector_pulled_divs=($(selector).filter("div").length!=0)
We'd need some code to work with to help you further.

You can check with nodeName property:
if ($(".selector").get(0).nodeName == 'div') { \\do stuff }

I think you're trying to do something:
if( $('#selector').length ) {
// do something if selector pulled a div
} else {
// do something if selector not pulled a div
// for page redirect write following line
window.location = 'YOUR_URL';
}
$('#selector').length will check the exists of div with id=selector.

jquery simple modal help on window load

I'm trying to something like this if in the html there is a div called "#super" load it in the simple modal if not do nothing. I managed to do this with the my skill :D which is none: to load the modal if the #super exists, but it still loads doesn't matter if it exitst or not. PLease help I'm absolute noob on jquery.
if( $('super') ){ $("#super").modal({onOpen: function (dialog) {
dialog.overlay.fadeIn('slow', function () {
dialog.container.slideDown('slow', function () {
dialog.data.fadeIn('slow');
});
});
}});
I'm using this jquery plugin link text

If #super does not exist, nothing will happen. So, the following should fit your needs:
$("#super").modal({onOpen: function (dialog) {
dialog.overlay.fadeIn('slow', function () {
dialog.container.slideDown('slow', function () {
dialog.data.fadeIn('slow');
});
});
});

I'm not quite sure what it is that you want to do, in the if/else conditions, but to test for the existence of something:
if ($('#super').length) {
// it exists, do stuff
}
else {
// it doesn't exist, do other stuff. Or nothing
}
I'm sorry I can't be more specific, but I've not worked with the dialog/modal plugin.

The problem is this check
if( $('#super') )
will always return true, since the jQuery function always return a jQuery object which is not a false value.
Instead try this
if( $('#super').length > 0 )
