Combo Selection

[mr_ego]

This is my currect script:


document.main.title.value = window.opener.document.getElementById('title').innerHTML;
thebox.colour.selectedIndex = window.opener.document.getElementById('title').style.color;


yeah ... so basically i have a popup window with a select and text box in there and i need the select box to say the value of the parents' style from <div id=title>.

This script above doesnt work ... someone help!

at a guess, i'd say style.colour returns a hex colour value like '#FF0000' for red, or possibly the name of the colour eg 'red'. but selectedIndex is a number - the position of an item in a combo (SELECT) box. are you trying to get the combo to select the item 'red'? you'll have to make a script that goes through all the options and finds the one called 'red', then selects this one. eg.

var selectThisOne = 0
var colourName = window.opener.document.getElementById('title').style.color
for (i=0, i<thebox.colour.length, i++){
if (thebox.colour.options[i] = colourName){
selectThisOne=i
}
}
thebox.colour.selectedIndex=selectThisOne

ok?

The code Neil said is fine :


var selectThisOne = 0;
var colourName = window.opener.document.getElementById;('title').style.color
for (i=0, i<thebox.colour.length, i++){
if (thebox.colour.options[i] = colourName){
selectThisOne=i;
break;
}
}
thebox.colour.selectedIndex=selectThisOne;


Just added the break; because you don't need to loop thro' if you found the color!

sure, anything to cut out a few extra microseconds of processing.
