jquery - CSS 显示：弹性；在 IE 浏览器中无法正常工作

问题描述

我正在使用 Jquery 可拖动组件将元素添加到<p>.

我有以下问题

IE 浏览器显示不好的外观（见图）它显示all-scroll而不是Pointer

在此处输入图像描述

这是因为这个 CSS

p.given {
  display: flex;
  flex-wrap: wrap;
}

这个 CSS 我用来<p>正确显示内容。如果我删除该 CSS，有时会添加多个位置的可拖动组件。并且<p>内容在放置组件后进入下一行。你能建议什么代替flex吗？我无法删除这个 CSS ( p.given { display: flex; flex-wrap: wrap; })，因为如果我删除了<p>不灵活的内容，所以请给我一个解决方案来避免这个 IE 浏览器问题。

解决方案

首先，为什么要支持IE？这是一个非常古老的浏览器，有很多问题，特别是在开发中。我还注意到您使用 jQuery 1.12.4 和 jQueryUI 1.12.1。同样，它们是旧版本，会使您的代码变慢并且可能不安全。

至于解决方案，问题在于 contentEditable 选项。删除后，光标在 IE11 上显示正常。

我从没想过我会这么说，但是：我在 IE11 上测试过，它工作正常

这是新代码：

根据评论，我添加了一个新函数，该函数检查用户是否点击了 p 元素，然后将 contenteditable 设置为 true，否则将其设置为 false。这在 IE 上不太理想，但我认为这是您可以从该浏览器中获得的最大收益。

$(function() {
  function textWrapper(str, sp, btn) {
    if (sp == undefined) {
      sp = [0, 0];
    }
    var txt = "";
    if (btn) {
      txt = "<span class='w b'>" + str + "</span>";
    } else {
      txt = "<span class='w'>" + str + "</span>";
    }

    if (sp[0]) {
      txt = "&nbsp;" + txt;
    }

    if (sp[1]) {
      txt = txt + "&nbsp;";
    }

    return txt;
  }

  function chunkWords(p) {
    var words = p.split(" ");
    words[0] = textWrapper(words[0], [0, 1]);
    var i;
    for (i = 1; i < words.length; i++) {
      var re = /\[.+\]/;
      if (re.test(words[i])) {
        var b = makeTextBox(words[i].slice(1, -1));
        words[i] = "&nbsp;" + b.prop("outerHTML") + "&nbsp;";
      } else {
        if (words[0].indexOf(".")) {
          words[i] = textWrapper(words[i], [1, 0]);
        } else {
          words[i] = textWrapper(words[i], [1, 1]);
        }
      }
    }
    return words.join("");
  }

  function unChunkWords(tObj) {
    var words = [];
    $(".w", tObj).each(function(i, el) {
      console.log($(el).text(), $(el).attr("class"));
      if ($(el).hasClass("b")) {
        words.push("[" + $(el).text().trim() + "]");
      } else {
        words.push($(el).text().trim());
      }
    });
    return words.join(" ");
  }

  function makeBtn(tObj) {
    var btn = $("<span>", {
      class: "ui-icon ui-icon-close"
    }).appendTo(tObj);
  }

  function makeTextBox(txt) {
    var sp = $("<span>", {
      class: "w b"
    }).html(txt);
    makeBtn(sp);
    return sp;
  }

  function makeDropText(obj) {
    return obj.droppable({
      drop: function(e, ui) {
        var txt = ui.draggable.text();
        var newSpan = textWrapper(txt, [1, 0], 1);
        $(this).after(newSpan);
        makeBtn($(this).next("span.w"));
        makeDropText($(this).next("span.w"));
        $("span.w.ui-state-highlight").removeClass("ui-state-highlight");
      },
      over: function(e, ui) {
        $(this).add($(this).next("span.w")).addClass("ui-state-highlight");
      },
      out: function() {
        $(this).add($(this).next("span.w")).removeClass("ui-state-highlight");
      }
    });
  }

  $("p.given").html(chunkWords($("p.given").text()));

  $("p.given").on("click", ".b > .ui-icon", function() {
    $(this).parent().remove();
  });

  $("p.given").blur(function() {
    var w = unChunkWords($(this));
    console.log(w);
    $(this).html(chunkWords(w));
    makeDropText($("p.given span.w"));
  });

  $("span.given").draggable({
    helper: "clone",
    revert: "invalid"
  });

  makeDropText($("p.given span.w"));
  /**
   * New function. Check document click event and see if use clicked
   * inside or outside the p.given element then set contenteditable
   * accordingly.
   */
  $(document).on("click", function(e) {
    let pElement = jQuery(e.target).closest("p.given");
    let check = !$(event.target).is("p.given") && !$(event.target).parents("p.given").is("p.given");

    if (check) {
      $("p.given").attr("contenteditable", "false");
    } else {
      $("p.given").attr("contenteditable", "true").focus();
    }
