CSS显示:flex;在IE浏览器中无法正常工作 [英] CSS display: flex; not working properly in IE browser

本文介绍了CSS显示:flex;在IE浏览器中无法正常工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

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浏览器显示不良外观(请参见图片)它显示all-scroll而不是Pointer

发生这种情况是由于此CSS 

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

此CSS我曾用来正确显示<p>内容.如果我删除了该CSS，可拖动组件有时会在其中添加多个位置.以及<p>内容将在放置组件之后移至下一行.除了flex，您还能提出其他建议吗?我无法删除此CSS(p.given { display: flex; flex-wrap: wrap; })，因为如果我删除了<p>内容的灵活性不佳，那么请给我一个解决方案，以避免此IE浏览器问题.

解决方案

首先，为什么支持IE?这是一个非常古老的浏览器，存在很多问题，尤其是在开发中.我还注意到您使用了jQuery 1.12.4和jQueryUI 1.12.1.同样，它们是旧版本，使您的代码运行缓慢且可能不安全.

对于解决方案，问题在于contentEditable选项.删除后，光标将在IE11上显示为正常.

我从没想过要这么说，但是:我在IE11上进行了测试，并且正常运行

这是新代码:

基于注释，我添加了一个新函数，该函数检查是否使用了单击p元素，然后将contenteditable设置为true，否则将其设置为false.这在IE上并不理想，但是我认为这是您可以从该浏览器中获得的最大体验.

 $(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");

    let check = !$(event.target).is("p.given") && !$(event.target).parents("p.given").is("p.given");

I'm using Jquery draggable component to add an element to <p>.

I have following issue

IE browser showing bad look(see the image) It shows all-scroll instead of Pointer

this happens because of this CSS

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

this CSS I used to display the <p> content properly. If I remove that CSS, draggable component adding multiple places to sometimes. and also <p> contents going to the next lines after drop components. Can you suggest anything instead of flex? I can't remove this CSS (p.given { display: flex; flex-wrap: wrap; }), because if I remove that <p> content not flexible properly, So please give me a solution to avoid this IE browser issue.

$(function() {
  function textWrapper(str, sp, btn) {

解决方案

Firstly, why support IE? It's a very old browser that has many issues particularly in development. I also noticed that you use jQuery 1.12.4 and jQueryUI 1.12.1. Again, they are old versions that makes your code slow and possibly insecure.

As for the solution, the problem lies in contentEditable option. Once removed the cursor appears normal on IE11.

I never thought I would say this but: I tested on IE11 and it worked normally

Here is the new code:

based on the comment I added a new function that checks if use clicked on p element then sets contenteditable to true, otherwise it will set it to false. This is less than ideal on IE but I think this is the most you can get out of that browser.

$(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");

  makeDropText($("p.given span.w"));
  /**

   * 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");
