facebook喜欢hashtags - 自动换行:break-word;不适用于FF和IE9 +

我试图在<b>时插入keyup,检测到#(如Facebook)。我从textarea读取,并复制到div元素。

    <div  class="new_postAdDescription2" id="new_postAdDescription2" spellcheck='false' contenteditable='true'> </div>  
    <textarea name="description" id="new_postAdDescription" spellcheck='false' 
class="new_postAdDescription" cols="30" rows="10" placeholder="Posto nj&euml; shpallje" >
</textarea>

请查看我如何更换空格和新线条。我也试过了&nbsp;(顺便说一句,如果我删除空格匹配,一切正常!)

$('#new_postAdDescription').keyup(function (e) {
        var str = $('#new_postAdDescription').val();

        str = str.replace(/ /g, '&#160;');
        str = str.replace(/\n/g, '<br/> ');

        str = str.replace(/(&#160;|<br\/> )#([a-zA-Z0-9]+)/g, "$1<b class='highlighterContent'>#$2</b>");

        $('#new_postAdDescription2').html(str);  
    });

//风格

<style>
.new_postAdDescription, .new_postAdDescription2{
    position: relative;
    float: left;
    background-color: transparent;
    border: 0;
        -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */
    outline: 0;
    width: 694px;
    color:#1c1c1c;
    resize: none;
    margin: 10px;
    height: 115px;
    font-size:13px;
    line-height:1.3;
    direction: ltr; 
    word-wrap:break-word;
}

.new_postAdDescription2{
position:absolute;
color:transparent;
word-wrap:break-word;
direction: ltr; 
text-align: left;
}
.highlighterContent{
position:relative;
font-weight:bold;
color:#333;
background-color:#f2f2f2;
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */
}

</style>

这不是最好的,但它适用于Chrome,但在FF和IE9上,当涉及到破坏这个词时,它会重叠文本并失去跟踪。看屏幕截图

<{1}}和FF

我确实找到了正确的答案......

新的javascript(更简单):

$('#new_postAdDescription').keyup(function (e) {
    var str =$('#new_postAdDescription').val();

    str = str.replace(/\n/g, '<br>');
    str = str.replace(/#([a-zA-Z0-9]+)/g, "<b>#$1</b>");

    $('#new_postAdDescription2').html(str);
});

和in css:

.new_postAdDescription, .new_postAdDescription2{
    position: relative;
    float: left;
    background-color: transparent;
    border: 0;
    outline: 0;
    width: 694px;
    resize: none;
    margin: 10px;
    height: 115px;
    font-size:13px;
    line-height:1.3;
    direction: ltr;
    color:#1c1c1c;
}

.new_postAdDescription2{
    position:absolute;
    color:transparent;
    white-space: pre-wrap;
}
b{
font-weight:bold;
color:#333;
display: inline-block;
white-space: pre-wrap;
word-wrap:break-word;
direction: ltr; 
text-align: left;
max-width: 100%;
}

添加白色空间:预包装;在正确的地方使它工作。
