How do you loop a string inside an alert box?

First of all you are doing it wrong. 'alert' function takes sting as a parameter. So the for loop which you are trying to invoke inside 'alert' will not work. Second the 'print' function you are using is actually used to print the page if used correctly. Source: https://developer.mozilla.org/en-US/docs/DOM/window.alert, http://stackoverflow.com/questions/1247040/how-does-the-javascript-print-function-work-can-i-create-a-document-using-javas, http://www.htmlgoodies.com/beyond/javascript/article.php/3471121/Print-a-Web-Page-Using-JavaScript.htm So how to do it? Fairly simple loop on variable 'text' outside of alert and take the value in some other variable and finally alert this other variable. Below is the snippet. var text = 'Hello'; var text_to_repeat = ''; for(i=0; i<100; i++){ text_to_repeat += text; } alert(text_to_repeat);

i wish to add a few more terms here in the output. suppose of we want to generate a random number and the alert box should show the random number generated and the number of stars equal to that number. eg. if the random number is 5, then the box should say " 5. *****" var x = Math.floor(( Math.random() * 8) + 1) var j = '*' for( var i=0; i<=x; i++) { j =  j + '*' } alert(x + j) This is what i was trying, but didn't work. What changes are to made?
