Hi, can someone please show me how to most elegently do this?.....
I have a textbox, and I want to search the contents of it and replace all instances of a certain word, and replace that word with something else. For the purposes of this it could be replacing "green" with "blue". Can someone please show me how to properly do this? :) Sincerest regards, Alxasa. |

Re: show me how to replace all instances of word in textbox
I am sorry I moved too fast... I now do understand / /gi tags around
apple. If apples was a var reference to a parent frame, like 'parent.somestring' instead of just putting a word in there, how would that work? :) Thank you so much for your assistance. Have a great day! :) re = /(parent.somestring)/gi ? |

Here was the code I am talking about: <script type="text/javascript"> function ReplaceApples() { //--- setup regex string re = /apples/gi; <--- want to put a top.value="apples" in between / /gi //---- get element id = document.getElementById("sunny"); //--- get text within element str = id.value; //--- do regex replace newstr=str.replace(re, "oranges"); //--- save new value back to element id.value = newstr; } </script> |
