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 një shpallje" >
</textarea>
请查看我如何更换空格和新线条。我也试过了
(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, ' ');
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);
});
//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
中的
在
IE9
中:
答案 0 :(得分:1)
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。
