Calculator Widget Menu

With Formloop you can configure a customized calculator widget and then copy a piece of code and integrate it on your homepage.

Responsive Calculator Widgets

If you are using the javascript you can set the height and width of the widget in the javascript, so it suits your design. When using responsive design for mobile-devices the feature with adjustable width is very convenient since you can float objects downwards. We have added example code in the bottom of this page for testing our service.

Information and recommendations

The free version of the API for converters and formula calculators gives you 6 calls per minute and 20 calls per day.

Orange text is the code parts of the text.

Use the variables in the javascript when you have a dynamic page and or responsive design or if you want to change an existing widget that you are using. Arguments that can be sent to modify your widgets are:

var langcode="en" Sets the language to English.
var height="100" Sets the height to 100 px on the widget.
var width="100" Sets the width to 100 px on the widget.
var mobile="TRUE" Sets the widget in mobile mode.

Usually what users of our code do is that for mobile pages the widget is exchanged with a button to the Mobile version of the widget instead.
When no arguments regarding height or width is used the calculator widget will have the size that you set when you configured the widget.
When using a dynamic layout, remember to make space for when the widget unfolds and shows the result.

For the argument lang_code you can use any ISO language codes, for a list of language codes look at: language codes.

If you need some help in adding your url in WordPress look at Help Wordpress.

Testing your code for the first time close the web browser and open it to delete the session parameters. In some browsers pressing ctrl-F5 might do the trick.

If you want to use our widgets in a mobile application use the "Mobile Direct" and when configuring the widget press "Modify content & layout" and in there enable the back button option to get a back button back to your page.

When using our API or javascript without a license do not remove the div with the link, cause it will get you banned. You have the option to get the result from your calculation in an array, uncomment "alert(result.result_data[0]....." to get the result from the API.

Please mail us suggestions for improvement or settings that you might want to change dynamically.

Finally some last words, a mail with instructions have been sent to the mail address that you supplied and if you are logged in you can always go back and copy your code again by choosing Created Widgets from the menu Create Widgets & Apps.
