I need to use Substring in Javascript. But despite my searches, i have an error : substr seems to be unknown...
function confirm_ticket(idAgir,TempsEstime) {
var str = TempsEstime;
var strConcatenate = TempsEstime.substr(0, 2) + ":" + TempsEstime.substr(2, 2);
alert("confirmer le temps de maintenance de " + strConcatenate + " min pour le ticket " + idAgir);
}
Is there anything wrong in this ? thanks in advance
The substr and substring methods in JavaScript are bound to the String object, so they only work on string types. Use the typeof keyword to determine what time you are applying the methods to.
substr takes two arguments: 1) which index to start, 2) how many characters
substring takes two arguments: 1)which index to start, 2) which index to end
EDIT: The white space formatting was jumbled.
I think you're looking for substring()
http://www.w3schools.com/jsref/jsref_substring.asp
function confirm_ticket(idAgir,TempsEstime) {
var str = TempsEstime;
var strConcatenate = TempsEstime.substring(0, 2) + ":" + TempsEstime.substring(2, 2);
alert("confirmer le temps de maintenance de " + strConcatenate + " min pour le ticket " + idAgir);
}
Try using .substring() and see if that works.
Another thing to notice, make sure the type of 'TempsEstime' is a string.
you have to use substring() method:
<script type="text/javascript">
var str="Hello world!";
document.write(str.substring(3)+"<br />");
document.write(str.substring(3,7));
</script>
