javascript - Random font size and set a min and max of the character -


i have few problems here.

a)how add random font size code?

b)how set limitation of min(3) , max(8) characters?

javascript

function randomstring(length) {   var text = "";   var possible = "abcdefghijklmnopqrstuvwxyz";   (var = 0; < length; i++)     text += possible.charat(math.floor(math.random() * possible.length));   return text; } function changingrandomstring(length) {   setinterval(function () {     document.getelementbyid("random").innerhtml = randomstring(length);   }, 2000); }

for adding random fond size 

document.getelementbyid("myp").style.fontsize = math.floor((math.random() * 8) + 3)+"px";

you have implement own code randomize it

how set limitation of min(3) , max(8) characters?

function randomstring(length) {    if(length < 3) length = 3;     if(length > 8) length = 8;

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 <...
