下面是一個單空間js解決方案,與scott everden的jquery示例一起使用。我只在firefox中測試過,但這應該足夠開始了。

javascript

var MIN_SPACES_BETWEEN_VALS = 3;

function mkOption(left, right, total)

{

var str = left;

var spaces = total - left.length - right.length;

for(x = 0;x < spaces;x++)

str += "\xA0";

var opt = document.createElement("option");

opt.text = str + right;

opt.value = right;

return opt;

}

function populate(selId, vals)

{

var sel = document.getElementById(selId);

var maxLeft = -1;

var maxRight = -1;

for(idx = 0;idx < vals.length;idx++)

{

if(vals[idx][0].length > maxLeft)

maxLeft = vals[idx][0].length;

if(vals[idx][1].length > maxRight)

maxRight = vals[idx][1].length;

}

var total = maxLeft + maxRight + MIN_SPACES_BETWEEN_VALS;

for(idx = 0;idx < vals.length;idx++)

sel.add(mkOption(vals[idx][0], vals[idx][1], total), null);

}

HTML

select

{

font-family: Courier, mono;

}

var vals = [["Afghanistan", "+93"], ["Albania", "+355"], ["Algeria", "+213"]];

populate("countryCallingCode", vals);
