带有调整列的HTML多列下拉列表

标签： html html5

我需要一个包含多列的下拉菜单。我用Google搜索并找到了解决方案：

<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>

但是，列不会相互调整。

外观如何：

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

我希望它看起来像：

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

据我所知，

select内部的HTML不是有效的，但使用jquery（http://jsfiddle.net/upgradellc/ASR2K/2）并不难解决：

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>

的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，确保字体排成一行：

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

此解决方案不需要特定字体，它会使用您的字体测量文本。

缩小两列之间的空格有一个“神奇的数字”，这个数字越大，列越近，但是如果它太大，则函数将无效（我使用60和我的字体{ {1}}）。

使用您的字体添加css 

Verdana 12px

在页面中添加范围

.measuring {
    font-size: 12px;
    font-family: Verdana,Arial,sans-serif;
    display:none;
}

使用函数<span id="measuring" class="measuring"></span> 。

twoColumnDropDown()

说明：

  • function twoColumnDropDown(dd, separatorChars, magicNumber) { var biggestLength = 0; $(dd).find('option').each(function () { $("#measuring").text($(this).text().replace(separatorChars, '')); if ($("#measuring").width() > biggestLength) { biggestLength = $("#measuring").width(); } }); biggestLength = biggestLength - magicNumber; $(dd).find('option').each(function () { if ($(this).text() != "") { var parts = $(this).text().split(separatorChars); $("#measuring").text(parts[0]); $(this).text(parts[0] + String.fromCharCode(8202).repeat(biggestLength - $("#measuring").width()) + parts[1]); } }); } =选择元素
  • dd =通常separatorChars
  • "-" =先前已解释

这可以通过div，css和jquery（http://jsfiddle.net/5hvd6k83/68/）来解决。

HTML：

<textarea id="textarea" style="width:250px;height:100px;"></textarea>
<div class="dropdown">
  <div id="myDropdown" class="dropdown-content">
    <a>
      <div class="container">
        <div class="block word">con</div>
        <div class="block prob">20%</div>
        </div>
    </a>
    <a>
      <div class="container">
        <div class="block word">constant</div>
        <div class="block prob">20%</div>
        </div>
    </a>
  </div>
</div>

CSS：

.container {
  display: flex;
  flex-wrap: wrap;
  justify-content: space-between;
  vertical-align: middle;
}

.block {
  width: 60px;
  height: auto;
  margin: 3px;
  overflow: hidden;
}



.word {
  text-align: left;
}

.prob {
  text-align: right;
}


.dropdown-content {
  display: none;
  background-color: #f1f1f1;
  width: 300px;
  height: auto;
  overflow: auto;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.5);
  z-index: 1;
}

.dropdown-content a {
  color: black;
  display: block;
}

// .dropdown a:hover { background-color: #ddd; }
.show { display: block; }

Javascript：

const items = document.querySelectorAll("#myDropdown > a");

var preItem, currItem;

var tabCnt = 0;
const itemLen = items.length;

document.getElementById("myDropdown").classList.toggle("show");


$(document).delegate('#textarea', 'keydown', function(e) {
    var keyCode = e.keyCode || e.which;
  if (keyCode == 9) {
    e.preventDefault();
    currItem = items[tabCnt % itemLen];
    currItem.style.backgroundColor = 'lightblue';
    tabCnt += 1;
    if (preItem) {
        preItem.style.backgroundColor = '';
    }
    var word = $(currItem).find('.word');
    $('#textarea').text($(word).text());
    preItem = currItem;
  }
});

结果： Result
