I have two page page1.php, page2.php and one JS file Control.js.
In page1.php
HTML :
<img src="images/b.jpg" width="31" height="26" id="imgClick1" onClick="return changeImage1(this)" >
In Control.js
function changeImage1() {
document.getElementById("imgClick1").src = "images/b.jpg";
document.getElementById('num1').style.color = "#fff";
document.getElementById("text1").innerHTML = "Hello friend";
}
In page2.php
<div id="text1">
Hello world
</div>
So using JavaScript I am trying to write "hello friend" in the div "text1" of page page2.php when I click the image or the div of page1.php.
Is there any possible way to use JS to solve this problem?
Can we use any how document.getElementById("text1").innerHTML or something like that in the program?
I suggest you make use of the include function of php (provided you absolutely want to keep your text1 div on a separate page), like this on your page1.php file:
include('page2.php');
Make sure that when you do that, page1.php and page2.php are in the same folder, otherwise you may define a path to it like this:
include('/path/to/page2.php');

I have them both as HTML files in my repo. The button is just meant to switch from pages for now. I will add the function for the inputs and conditions later. I just want to get in working before I add anything. There are also no errors that or popping up. I cannot use a tag as I need to change the URL to pass data through it, so I need to have it in JS so I can change it with the data from the input.
The plan is to have the user put in their name in a text input, and have it inside the Url, then have the 2nd page process the name and output a text and photo.
This is the code that I have tried.
const nameButton = document.getElementById("nameBtn");
$(nameButton).click(function(){
preventDefault()
function change_page(){
window.location.replace("page-two.html");
};
change_page()
});
This is the Html:
<input class="font" type="text" id="inputName" value="Type in
your name..."></input>
<button class="fonts" id="nameBtn">Ready?</button>
</form>
</div>
</body>
<script src="scripts/script.js"></script>
</html>
Short answer, only replace the pathname
window.location.pathname = 'page-two.html'
In your case:
const nameButton = document.getElementById("nameBtn");
nameButton.addEventListener('click', function (event) {
event.preventDefault()
window.location.pathname = "page-two.html";
});

<script>
function addMoreAns() {
$(".add").append("<h1>Hi</h1>")
}
</script>
It is my jquery tag in javascript function.
jquery tag don't work under javascript function
You must have three things for your code to work:
You must make sure to have the JQuery library referenced prior to your use of any JQuery code.
In the HTML, you must have an element that is allowed to contain content with an add class.
You must invoke your function somehow. Just writing a function isn't the same thing as running it. You have to decide when the function should run and set up your code to invoke it at that point.
In the example below, the function is invoked every time the button is clicked.
document.querySelector("input[type=button]").addEventListener("click", addMoreAns);
function addMoreAns() {
$(".add").append("<h1>Hi</h1>")
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="button" value="Click to Add">
<div class="add"></div>
You need to load the jQuery library in the head of your page
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>

I want to check if a MySQL database contains a specific value. If it is true I want to hide a HTML <div>. Is this possible?
Can I hide elements with CSS & JS, or what should I use to hide the div?
Also, How would we add it in the Div like a NgIF statement
Thanks!
If you are seriously thinking about hiding the element with JavaScript (due to some kind of restriction or requirement). You can use following method.
CSS + Javascript + PHP way:
If you are thinking more like the Run code snippet section in Stack Overflow. Show expanded ONLY if it is set in database.
Then in that case you can implement something like this
$(function() {
$("#btnToggle").on("click", function() {
$("#comments").toggleClass("hide");
});
});
.hide {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!-- Hide using CSS way. Hide class can be echoed from your PHP based on the database value -->
<button type="button" id="btnToggle">Toggle hide/show</button>
<div id="comments" class="hide">Comment section to hide</div>
Try something like this in your PHP file. I have included an example of an item that is always rendered, and something that is conditionally rendered.
<div id="userinfo">
<?php // This is always rendered by the server ?>
Username: <?php htmlentities($row['username']) ?>
<?php // This is rendered by the server if the column is true ?>
<?php if ($row['admin']): ?>
<div class="admin">(admin)</div>
<?php endif ?>
</div>
Something along the line of
if (your statement condition) {
echo '<script type="text/javascript">document.getElementById(DIV_ID").style.display= "none";</script>';
exit;
}

I want to embedded the below jquery code in the following php variable $var
JQUERY Code:
<img src="images/image.png" id="Image1" alt="" style="width:30px;height:30px;">
PHP Code:
<?php $var = 'my_jquery_code'; return $var; ?>
You just need to escape the single quotes:
<?php
$var ='<img src="images/image.png" id="Image1" alt="" style="width:30px;height:30px;">';
return $var;
The only reasonable scenario I can think of where you would want to use onclick would be if you're dynamically loading the anchor element.
If so, this is probably better.
[script]
$(document).on('click', '.my_class_here', function() {
$('jQueryDialog1').dialog('open');
});
[/script]
[link_template]
...
[/link_template]
Then you would use AJAX or whatever voodoo you like to retrieve the link template (maybe while passing it some variables?) and add it to the page.
Alternatively, you can use $(document).find('.my_class_here').on('click', function... , but this is bad, performance wise.

I am working on a mobile application, I am trying to make an image as a button: I have an image and I want to click on it, then when I click the mobile gallery opens so that I can upload a photo.
Any help please?
I think, you want to open file-uploader on image button click! Right?
If so, you can use pure javascript / jQuery as following:
HTML:
<div id="profilepic">
<input id="fileSelector" type="file" name="file" accept="image/*" capture="camera" />
<button id="clickButton" onClick="openFileUpload();"><img src="Images/profilepic.png" width="170" height="170"/></button>
</div>
For jQuery append this to head of your document:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
Wrap following code in head too.
JQuery:
$(document).ready(function(){
$('#clickButton').on('click', function(){
$('#fileSelector').click();
});
});
OR Javascript:
function openFileUpload(){
document.getElementById('fileSelector').click();
}
http://jsfiddle.net/mas5qr1o/1/
See demo here:
jQuery DEMO
Javascript DEMO
Try the following jquery
$('#clickButton').on('click', function(){
$('#fileSelector').trigger('click');
});
