Using an external Javascript file associated with an HTML file. I was just curious how I could convert the above code into a workable Javascript code. There is a Calculate button on the HTML page so I need to use a calculate_click function I know. I have included the HTML and CSS I just need help writing the Javascript portion.[code]
View 4 RepliesDoes anyone know of a Javascript that will show an amount in a drop down based on what was selected in the previous drop down? Example: Code:
<select id="car">
<option value="volvo">Volvo</option>
<option value="audi">Audi</option>
</select>
<select id="price">
<option value="">Please select</option>
<!-- show this if volvo -->
<optgroup id="vol">
<option value="30000">30000</option>
<option value="31000">31000</option>
</optgroup>
<!-- show this if audi -->
<optgroup id="aud">
<option value="40000">40000</option>
<option value="41000">41000</option>
</optgroup>
</select>
I am having a little problem trying to show a loader (An animated GIF) while some request to a database happens. I have a page where the user selects a YEAR and when they select it with AJAX I perform a request to a database to get all the values for that specific year.
The problem is that there is a lot of information (4000+ records) that I need to query and show in a table (Actually I didn't use a table I use DIVs that look like a table), and when the user selects the year the webpage freezes for about 5 seconds and then it loads all of the data.
Is there a way to sort of show an image loader gif while the data is being gotten? I tried putting the loader image in the DIV container while no year is selected and then once the request is done, I substitute the DIV container's contents (The image loader) for the data from the database.
