我试图在<b>
上检测到keyup
时(例如#
)插入Facebook
。我从textarea
读取,然后复制到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 një shpallje" >
</textarea>
请查看我如何替换空白和换行符。我也尝试过
(顺便说一句,如果删除空白匹配,一切正常!)$('#new_postAdDescription').keyup(function (e) {
var str = $('#new_postAdDescription').val();
str = str.replace(/ /g, ' ');
str = str.replace(/\n/g, '<br/> ');
str = str.replace(/( |<br\/> )#([a-zA-Z0-9]+)/g, "$1<b class='highlighterContent'>#$2</b>");
$('#new_postAdDescription2').html(str);
});
//样式
<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>
这不是最好的方法,但是它在Chrome上可以正常工作,但是在FF和IE9上,当涉及到单词破译时,它会与文本重叠并失去踪迹。看到屏幕截图
在
FF
和IE9
中在
Chrome
中时: 最佳答案
我确实找到了正确的答案....
新的javascript是(简单得多):
$('#new_postAdDescription').keyup(function (e) {
var str =$('#new_postAdDescription').val();
str = str.replace(/\n/g, '<br>');
str = str.replace(/#([a-zA-Z0-9]+)/g, "<b>#$1</b>");
$('#new_postAdDescription2').html(str);
});
和在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%;
}
添加空格:预包装;在正确的地方使它工作。
关于jquery - 像标签一样的facebook-word-wrap:break-word;在FF和IE9 +上不起作用,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/17215976/
