jquery - How to remove Firefox's enter-key with Javascript -

-

how can remove firefox's enter-key image below javascript?

i add more "(" , ")" code , works in ie, yet seems not work in firefox or chrome browsers.

moreover, please tell me differences between ie , firefox affect code.

enter image description here

here code:

javasript:

// extract labels adding "(" , ")" labels[i] = txt1 + "(" + txt + ")"; ... var str = document.getelementbyid("demo").innerhtml; alert(str); var res = str.replace(/(<br>)/g, ''); alert(res);

jsfiddle: http://jsfiddle.net/huydq91/l7vxl/

i think looking remove line break.

do this: 

// extract labels adding "(" , ")" labels[i] = txt1 + "(" + txt + ")"; ... var str = document.getelementbyid("demo").innerhtml; alert(str); var res = str.replace(/\n/g, ''); alert(res);

\n used match line breaks.
