Someone asked me whilst doing a job how to delete parts of a array within javascript, so just like other object oriented languages, you can have a array of data objects and each one can be accessible and removable. To achieve this with javascript you use the delete method as below.
var myArray = new Array(); myArray[0] = "first value"; myArray[1] = "second value"; // and to delete the second value delete myArray[1]; |
Someone contacted me about adding some numbers together with comma’s and dots within there values, here is the email via the contact me page.
“Please I need a javascript code that can enable me add two or more numbers containing dot(.) and/or comma (,) together. For example, 122.34 + 233.56. Or/And 233,239.34 + 323,322.44. Thanks in advance.”
Here is the code that will accomplish the request.
<html> <script type="text/javascript" > function load() { var value1="233,122.34"; var value2="233.56"; alert(parseFloat(value1.replace(",",""))+parseFloat(value2.replace(",",""))); } </script> <body onload="load()"> </body> </html> |
The main part is the parseFloat and replacing the “,” with nothing “” to remove the none float characters via the object replace method.
