very simple question! i was wondering how to use javascript to alert something in my textbox...not sure what i'm doing now is not working. heres the function
function alertNow(comment){
alert(comment);
}
now here is the textbox
<input type = 'text' name = 'txt_comment'>
<button onClick = alertNow(txt_comment.value) value = "Submit Comment"></button>
sure this is doable, i did it before but i just forgot some syntax prob. any ideas? thanks!
You are missing quotations. Also use the ID instead of name.
<input type = 'text' name = 'txt_comment' id='txt_comment'>
<button onClick = 'alertNow(txt_comment.value)' value = "Submit Comment"></button>
Also better to use, document.getElementById like below
<button onClick = 'alertNow(document.getElementById("txt_comment").value)' value = "Submit Comment"></button>
<input type="text" id="testTextarea">
<input type="submit" value="Test" onClick="alert(document.getElementById('testTextarea').value);" />
function alertNow() {
var a = document.getElementById("txt_comment").value;
alert (a);
}
<input type = 'text' name = 'txt_comment' id="txt_comment">
<button onClick = "alertNow()" value= "Submit Comment"></button>
here is the code to complete your task...
// js code ...
function alertNow(){
alert(document.getElementById('txt_comment').value);
return false;
}
// html code ....
<form name="form_1" id="form_1" method="post">
<input type = 'text' id='txt_comment' name = 'txt_comment'>
<input type="button" onClick = "return alertNow();" value = "Submit Comment"/>
</form>
Use the ID instead of name.
function alertText() {
alert(document.getElementById('txt_comment').value);
}
<input type = 'text' name = 'txt_comment' id="txt_comment">
<button onClick = "alertText()" value= "Submit Comment"></button>
