javascript - Trying to replace document.write to a innerHTML but it doesn't work -

so i'm making code assignment have make loop multiplication table input variables i've gotten table work want input a<div id='buffer'></div> , not using 'document.write'.

var _buffer = document.getelementbyid('buffer'); var rows=prompt("enter rows"); var columns=prompt('enter columns'); document.write("<table border='1'>"); (var a=1; < rows ; a++) {     document.write("<tr>");     for(var b=1; b< columns; b++) {         document.write("<td>"+a*b+"</td>");     }     document.write("</tr>"); } document.write("</table>"); 

i want use _buffer.innerhtml instead of document.write when change out the code doesn't print information in table looking , suggestions thanks!

you can initialize variable (t in example below), , put text string, assign innerhtml:

var _buffer = document.getelementbyid('buffer'); var rows=prompt("enter rows"); var columns=prompt('enter columns');  var t = "<table border='1'>"; (var a=1; < rows ; a++) {     t = t + "<tr>";     for(var b=1; b< columns; b++) {         t = t + "<td>"+a*b+"</td>";     }     t = t + "</tr>"; } t = t + "</table>";  _buffer.innerhtml = t;
