javascript - How do you sum two values containing the dollar sign "$"? I have been trying to figure out the methods and properties, still no clue - 


//for example  allinputs[22].value //equals $45 , allinputs[4].value  // equals $70  allinputs[22].value + allinputs[4].value = "$45$70"

it equals "$45$70". want sum value. how sum both values final value ignoring dollar sign?

you can use 

"$" + (parseint(allinputs[22].value.substring(1)) + parseint(allinputs[22].value.substring(1)))

the substring method, rid of $ sign, , parseint convert number. need that, because if not use concatenate values strings. note put set of brackets sum numbers. because, when interpreter sees "$" thinks should concatenate strings. want sum numbers , concatenate sum "$" string.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
