select all the options

tyris · May 16, 2001

hi all,
i do have a multiple option :

<SELECT NAME="display_list" MULTIPLE style="HEIGHT: 87px; WIDTH: 115px">
<OPTION VALUE="Project start date">Project start date
<OPTION VALUE="Quote Status">Quote Status
<OPTION VALUE="Quote Closed Date">Quote Closed Date
<OPTION VALUE="Prj desc.">Prj desc.
<OPTION VALUE="BDD">BDD</OPTION>
</SELECT>

what i'd like is that when i click a button all the options become selected, what kind of function should i call from my button ? Best regards X-),

ok tyris,looks like you are working a lot in JS.
heres something i tried.
------------------------------------------------------------
<html>
<script>
function selectall()
{

for(var i=0;i<document.multiselect.display_list.length;i++)
{
document.multiselect.display_list.option.selected=true;
}
}
</script>
<body>
<form name="multiselect">
<SELECT NAME="display_list" MULTIPLE style="HEIGHT: 87px; WIDTH: 115px">
<OPTION VALUE="Project start date">Project start date
<OPTION VALUE="Quote Status">Quote Status
<OPTION VALUE="Quote Closed Date">Quote Closed Date
<OPTION VALUE="Prj desc.">Prj desc.
<OPTION VALUE="BDD">BDD</OPTION>
</SELECT>
<p><input type="button" value="Select All" name="submit" onClick="selectall()"></p>
</form>
</html>

hi a correction---
it should be options in the script code.
the function should be---
function selectall()
{

for(var i=0;i<document.multiselect.display_list.length;i++)
{
document.multiselect.display_list.options.selected=true;
}
}
</script>

hey i don't understand...when i try to type a square bracket this editor does not accept it!
the code is---
function selectall()
{

for(var i=0;i<document.multiselect.display_list.length;i++)
{
document.multiselect.display_list.options squareBracketOpen i squareBracketClose.selected=true;
}
}

The problem with square brackets is probably related to the TGML markup tags you can uses to specify html-like attributes to your message. Try putting (open-square-bracket)code(close-sequare-bracket) and (open-square-bracket)/code(close-sequare-bracket) around your code. Also use the "Preview Post" button to see if your code was interpreted correctly.
