Come impostare il valore nel menu a

Question

giù ho quel codice:

</script> 
<!-- End HTML Area --> 
</div> 
</td> 
</tr> 
<tr> 
<td height='47' colspan='4'></td> 
<td colspan='13' valign='top' align='right'> 
<table cellpadding='0' cellspacing='0' cols='1' class='PSGROUPBOXWBO' width='934'> 
<tr><td class='PSGROUPBOXLABEL' align='right'><a name='DERIVED_RC_IRSL_MT_TRIPLE_GB' id='DERIVED_RC_IRSL_MT_TRIPLE_GB' tabindex='-1' href="javascript:submitAction_win6(document.win6,'DERIVED_RC_IRSL_MT_TRIPLE_GB');"><img src='/cs/crmprod/cache/PT_COLLAPSE_HEB_1.gif' alt='הסתרת הנתונים' title='הסתרת הנתונים' border='0' /></a>&nbsp;סיווג פניה לאחר טיפול בלקוח&nbsp;</td></tr> 
<tr><td width='932'> 
<table id='ACE_width' border='0' cellpadding='0' cellspacing='0' cols='10' width='932' class='PSGROUPBOX' style='border-style:none' > 
<tr> 
<td width='0' height='4'></td> 
<td width='70'></td> 
<td width='3'></td> 
<td width='246'></td> 
<td width='41'></td> 
<td width='3'></td> 
<td width='247'></td> 
<td width='49'></td> 
<td width='3'></td> 
<td width='270'></td> 
</tr> 
<tr> 
<td height='4' colspan='3'></td> 
<td rowspan='2' valign='top' align='right'> 
<select name='MT_CASE_EXTRA_MT_CAT_SEQ_NUM' id='MT_CASE_EXTRA_MT_CAT_SEQ_NUM' tabindex='360' size='1' class='PSDROPDOWNLIST' style="width:207px; " onchange="if (document.readyState == 'complete') submitAction_win6(this.form,this.name);" > 
<option value="0" selected='selected'></option> 
<option value="21">test</option> 
<option value="23">test2</option> 
<option value="64">test3</option> 
<option value="41">test4</option> 
<option value="61">test5</option> 
<option value="141">test6</option> 
<option value="22">test7</option> 
<option value="63">test8</option> 
<option value="24">test9</option> 
</select> 

cerco di rendere il codice JavaScript. Quando l'utente lo copia e lo incolla nel campo dell'indirizzo nel browser, il valore desiderato verrà automaticamente selezionato nel menu.

Ecco quello che faccio:

javascript:function GetSelectedItem() {  
    var e = document.getElementById("selected24"); 
    var strSel = "The Value is: " + e.options[e.selectedIndex].value + " and text is: " + e.options[e.selectedIndex].text; 
    alert(strSel); 
    }

Se si desidera impostare il valore selezionato di vostro elemento <select>, si dovrebbe fare in questo modo:

var newValue = 24; // or whatever 
document.getElementById('MT_CASE_EXTRA_MT_CAT_SEQ_NUM').value = newValue;
