问题描述

我需要一个包含多列的下拉菜单。我搜索了一下,发现了一个解决方案:

 < select name =timezones> 
< option value =1>
< column> Pacific / Auckland< / column>
< column> +12:00< / column>
< / option>
< option value =2>
<专栏>澳大利亚/布里斯班< /< />
< column> +10:00< / column>
< / option>
< / select>

然而,这些列并未相互调整。



$ p
$ b $ pre $ 太平洋/奥克兰+12:00
澳大利亚/布里斯班+10: 00

我想如何看起来像:

 太平洋/奥克兰+12:00 
澳大利亚/布里斯班+10:00

$ b $在一个选择的内部是无效的HTML据我所知,但这并不难用jquery解决( http://jsfiddle.net/upgradellc/ASR2K/2 ):

html:

 < select name =timezonesid =timezones> 
< option value =1> Pacific / Auckland +12:00< / option>
< option value =2>澳大利亚/布里斯班+10:00< / option>
< option value =3> Aust +10:00< / option>
< option value =3> A +10:00< / option>
< / select>

javascript:

  var spacesToAdd = 5; 
var maximumLength = 0;
$(#timezones option)。each(function(){
var len = $(this).text()。length;
if(len> largestLength){
largestLength = len;
}
});
var padLength = largestLength + spacesToAdd;
$(#timezones option)。each(function(){
var parts = $(this).text()。split('+');
var strLength = parts [0] .length;
for(var x = 0; x <(padLength-strLength); x ++){
parts [0] = parts [0] +'';
}
$(this).text(parts [0] .replace(/ / g,'\\\ ')+'+'+ parts [1])。text;
});

css,确保字体排列齐整:

  select {
font-family:Courier New,Courier,monospace
}


I need a drop down menu with multiple columns. I googled and found a solution:

<select name="timezones">
    <option value="1">
        <column>Pacific/Auckland</column>
        <column>+12:00</column>
    </option>
    <option value="2">
        <column>Australia/Brisbane</column>
        <column>+10:00</column>
    </option>
</select>

However, the columns are not adjusted under each other.

How it looks:

Pacific/Auckland +12:00
Australia/Brisbane +10:00

How I want it looks like:

Pacific/Auckland    +12:00
Australia/Brisbane  +10:00

解决方案

inside of a select isn't valid HTML as far as I know, however this isn't hard to solve with jquery (http://jsfiddle.net/upgradellc/ASR2K/2):

html:

<select name="timezones" id="timezones">
    <option value="1">Pacific/Auckland +12:00 </option>
    <option value="2">Australia/Brisbane +10:00 </option>
     <option value="3">Aust +10:00 </option>
    <option value="3">A +10:00 </option>
</select>

javascript:

var spacesToAdd = 5;
var biggestLength = 0;
$("#timezones option").each(function(){
var len = $(this).text().length;
    if(len > biggestLength){
        biggestLength = len;
    }
});
var padLength = biggestLength + spacesToAdd;
$("#timezones option").each(function(){
    var parts = $(this).text().split('+');
    var strLength = parts[0].length;
    for(var x=0; x<(padLength-strLength); x++){
        parts[0] = parts[0]+' '; 
    }
    $(this).text(parts[0].replace(/ /g, '\u00a0')+'+'+parts[1]).text;
});

css, to make sure the fonts line up:

select{
    font-family:"Courier New", Courier, monospace
}
