How can I replace the text in an input field?

[dennisboys]

The replace method only works on a string with the first match substring. In the below example, how can I replace all 'a' with 'b'? Thanks in advance for any help!

    <script>
function replaceIt(){
	var textStore = document.getElementById("textInput").value;	
	var newText = textStore.replace("a","b");
	alert(newText);
};
	</script>
    

   
<input value="aaaabbbccc" type="text" id="textInput" name="textInput" />
<button onclick="replaceIt()">Replace all the a with b!</button>

<script type = "text/javascript">

function replaceIt(){
var textStore = document.getElementById("textInput").value;	
var newText = textStore.replace(/a/gi,"b");  // g means global, i means ignore case
alert(newText);
}
</script>
       
<input value="aaaabbbccc" type="text" id="textInput" name="textInput" />
<button onclick="replaceIt()">Replace all the a with b!</button>
