I've looked at a few other similar questions here and tried the following:
I am trying to access data from a SQLite3 database (which works fine), in an html file.
<script src="jquery-3.3.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).ready(){console.log("HELLO");}
</script>
I do not get the console message, no matter where I place it! It seems none of my jQuery is working.
Here's where I am trying to access the data:
<div class="panel-body">
The website you're most active on:
<select onchange="dropdown(this)">
<option value='PastHour'>Past Hour</option>
<option value='Past2Hours'>Past 2 Hours</option>
<option value='PastDay'>Past 24 Hours</option>
</select><br><br>
<script type="text/javascript">
if()
<b>Most Frequently Visited:</b><div id="most-freq"></div>
<b>Second Most Frequently Visited:</b><div id="most-freq-2"></div>
</div>
function dropdown(that) {
const requestURL = 'data/' + that.value;
jQuery.ajax ({
url: requestURL,
type: 'GET',
dataType: 'json',
success: (data) => {
console.log('data:', data);
console.log(data.Most);
console.log(data.SecMost);
jQuery('#most-freq').html(data.Most);
jQuery('#most-freq-2').html(data.SecMost);
}
})
}
</script>
I can access localhost/data and get the data I want to see, so I believe the app.get functions in my .js file are okay.
In addition to the data not being displayed or printed to console, I get the error message that dropdown is not defined. I think this is because of the scope, how could I change it?
Your code should be:
jQuery(document).ready(function () {console.log("HELLO");});
instead of:
jQuery(document).ready(){console.log("HELLO");}
It does not throws any error log because there is no error. Using the correct indentation it is easy to see the difference:
Correct behavior:
jQuery(document).ready(function () {
console.log("HELLO");
});
Wrong behavior:
jQuery(document).ready();
{
console.log("HELLO");
}
From JQuery ready's documentation link
JQuery has three way to execute javascript code when the DOM is fully loader. These are:
Example:
$(function(){ do something ... });
or
$(document).ready(function(){ do something .... });
Your Code function() is required. It specifies the function to run after the document is loaded
jQuery(document).ready(){console.log("HELLO");}
If you're still having trouble try this:
Ref: Code from https://learn.jquery.com/using-jquery-core/document-ready/
$( document ).ready(function() {
console.log( "ready!" );
});
jQuery don't is for debugging purposes. You can instance the console when something happens.
$('#buttonTest').click(function() {
console.log('you click on buttonTest');
// do something
});
For some reasons, the console object could be unavailable. Then you could check if it is - this is useful as you don't have to remove your debugging code when you deploy to production:
if (window.console && window.console.log) {
// console is available
}
and i suggest use the val with this method:
<select id="mySelect" onchange="myFunction($(this).val());">
<option value="testVaue">Ford F150<option>
</select>
function myfunction(mySelect){alert("my val from select: "+mySelect );}
