javascript - 如何使元素保持内联

Question

我正在使用面包屑系统，like this .我正在编写一些代码来使面包屑响应并在较小的屏幕上折叠。一切进展顺利，但我很难修复不守规矩的最终碎屑/页面标题。

在这种情况下，页面标题是“真的很长的标题以显示它如何破坏设计”，但它应该用点将自己切断，例如“真的很长的标题......”而不是中断到下一行。

我尝试了几个我创建的类，no-wrap 和 dot-overflow 但它们都没有成功。

出于某种原因，将 height 属性强制设置为 50px 或类似值以使其保持在一行中会导致下面的内容被碎屑覆盖的问题，并且仍然不会阻止文本跳到下一行。

JS fiddle :https://jsfiddle.net/7o1o81xa/

CSS

.no-wrap {
    white-space:nowrap;
}

.dot-overflow {
    overflow:hidden;
    text-overflow: ellipsis;
    white-space: nowrap;
}

HTML

<div class="breadcrumbs-compact-container">
  <div class="breadcrumbs-compact flat">
    <a href="#" class="active">Support</a>
    <a href="#">How To</a>
    <a href="#"><span class="dot-overflow no-wrap">Really long heading to show how it breaks the design</span></a>
  </div>
  <div style="clear: both;"></div>
</div>

您可以像下面这样提供使用媒体查询:

你可以改变你想要打破的宽度。并定义了最后一个链接的最大宽度。

@media screen and (max-width:700px){
  a.dot-overflow {
    max-width:200px;
  }
}

检查下面根据您的代码制作的代码片段。

var crumbLinkOriginalValues = new Array();

$(function() {
  checkCrumbSizePerpetual();
});

function checkCrumbSizePerpetual() {
  checkCrumbSize();
  $(window).resize(function() {
    checkCrumbSize();
  });
}

function checkCrumbSize(returnWidth) {
  var overallWidth = 0;
  $('.breadcrumbs-compact a:last-of-type').css('display', 'inline-block').addClass('dot-overflow');
  $('.breadcrumbs-compact a').each(function() {
    overallWidth += $(this).outerWidth();
  });
  if (returnWidth)
    return overallWidth;

  if (overallWidth > $(window).width()) {
    // minimize crumbs
    minimizeCrumbs();
  } else {
    // check if we need to maximize it
    maximizeCrumbs();
  }
}

function maximizeCrumbs() {
  if ($('.crumb-to-minimize').length)
    maximizeCrumbsLiteral();
}

function minimizeCrumbs() {
  var crumbLinks = $('.breadcrumbs-compact a');
  var crumbCounter = 1;
  crumbLinks.removeClass('crumb-to-minimize');
  crumbLinks.each(function() {
    var text = $(this).text();
    if (text != '...') {
      crumbLinkOriginalValues[crumbCounter - 1] = new Array();
      crumbLinkOriginalValues[crumbCounter - 1]['text'] = text;
      crumbLinkOriginalValues[crumbCounter - 1]['padding-left'] = $(this).css('padding-left');
      crumbLinkOriginalValues[crumbCounter - 1]['padding-right'] = $(this).css('padding-right');
      $(this).attr('title', $(this).text());
    }
    $(this).attr('data-crumb-counter-id', crumbCounter - 1);
    if (crumbCounter < crumbLinks.length)
      $(this).addClass('crumb-to-minimize');
    else
      minimizeCrumbsLiteral();
    crumbCounter++;
  });
}

function minimizeCrumbsLiteral(selfRan) {
  $('.breadcrumbs-compact a.crumb-to-minimize').text('...').css('padding-left', '25px').css('padding-right', '2px');
  $('.breadcrumbs-compact a:first-of-type').css('padding-left', '5px').css('padding-right', '5px');

  // check if first one needs to be reduced
  if (typeof selfRan != 'undefined' && !selfRan && checkCrumbSize(true) < $(window).width()) {
    $('.breadcrumbs-compact a:first-of-type').addClass('crumb-to-minimize');
    minimizeCrumbsLiteral(true);
  }
}

function maximizeCrumbsLiteral() {
  $(this).attr('data-crumb-counter-id');
  var crumbLinks = $('.breadcrumbs-compact a');
  crumbLinks.each(function() {
    var thisCrumbsVals = crumbLinkOriginalValues[$(this).attr('data-crumb-counter-id')];
    $(this).text(thisCrumbsVals['text']).css('padding-left', thisCrumbsVals['padding-left']).css('padding-right', thisCrumbsVals['padding-right']);
  });
