	Drop down setting How do I change the selected value of a dropdown list. I need to force this as if another part of the form changes this should change in sympathy. I have tried formObj.status.options[4].selected == true, but this doesn't work Sorted I had too many = 's "Paul" <notha@btopenworld.com> wrote in message news:KI-dnSvcY58GWdzbnZ2dnUVZ8turnZ2d@bt.com...

Do you want : show item 5 ? document.formObj.status.selectedIndex = 4; or : give a new value and new text to that item ? document.formObj.status.options[4].value = 'something.htm'; document.formObj.status.options[4].text = 'something'; or : whatelse ? if(document.formObj.status.selectedIndex == 4) alert(document.formObj.status.options[4].value); -- Stephane Moriaux et son (moins) vieux Mac dj dpass ASM said the following on 5/9/2007 9:15 AM: > Paul a crit : >> How do I change the selected value of a dropdown list.

I can barely copy/paste French into a translator so I am not sure what you are asking. It translates, roughly, to "What you say?" and I am not sure if you don't understand what I said or if it is a request for me to win the wager I offered to make. Just a friendly wager on whether or not I have to qualify formObj with document. before it. I don't. <input type="button" onclick="someFunction(this.form)" value="Test It"> function someFunction(formObj){ alert('I have a reference to formObj without using document. first') } Give it some thought and reconsider your statement that it "at least ... with document. in 1st place". Whether you need a document lookup depends - directly - on how you obtain formObj to start with. -- Randy Chance Favors The Prepared Mind comp.lang.javascript FAQ - http://jibbering.com/faq/index.html Javascript Best Practices - http://www.JavascriptToolbox.com/bestpractices/ Evertjan. a crit : > ASM wrote on 09 mei 2007 in comp.lang.javascript: >> Randy Webb a crit : >>> Wanna bet? >> quoi toi dire ? > How dire? do you mean 'document' is not necessary ? -- Stephane Moriaux et son (moins) vieux Mac dj dpass Stephane Moriaux and his (less) old Mac already out of date Randy Webb a crit : > ASM said the following on 5/9/2007 1:44 PM: >> Randy Webb a crit : >>> Wanna bet? >> quoi toi dire ? > I can barely copy/paste French into a translator so I am not sure what > you are asking.

You are the one who showed me that it works on either name or ID. -- -Lost Remove the extra words to reply by e-mail. Don't e-mail me. I am kidding. No I am not.
