"for loop" array
I was wondering if someone could help me with this. I am collecting numbers from each input with the class name 'totalrow'. That part is fine, but now I want to take all the results from each 'totalrow' and combine it into one final result. The 'totalrow's are generated dynamically through PHP.
If I put alert(total[i]); after 'total[i] = + document.getElem...' it alerts each of the correct values.
In a nutshell: I want to get all values from the 'totalrows' classname and add them together to alert the final total.
Code JavaScript:for (i=0;i<document.getElementsByTagName("input").length; i++) { var total = new Array(); if(document.getElementsByTagName("input").item(i).className == "totalrow"){ total[i] = + document.getElementsByTagName("input").item(i).value; } }
Any help is appreciated! Thanks!
