javascript - 在 Jquery 中输入文本

Question

伙计们，我想让我的输入文本变成两行。

这是我的 Demo

请检查这段代码

HTML

  <div id="container">

    <div class="writer">Hi! This is a test text. 
        <br><br>
        Can any one         
        Help me in this ?.</div>  

</div>

Java 脚本

var txt = $('.writer').text();
var timeOut;
var txtLen = txt.length;
var char = 0;
$('.writer').text('|');
(function typeIt() {   
    var humanize = Math.round(Math.random() * (200 - 30)) + 30;
    timeOut = setTimeout(function() {
        char++;
        var type = txt.substring(0, char);
        $('.writer').text(type + '|');
        typeIt();

        if (char == txtLen) {
            $('.writer').text($('.writer').text().slice(0, -1)); // remove the '|'
            clearTimeout(timeOut);
        }

    }, humanize);
}());

Answer 1

您可以添加 white-space: pre-line;向 .writer 声明以换行，如下所示:

.writer {
    font:bold 23px arial;
    white-space: pre-line;
}

WORKING DEMO

16.6 White space: the 'white-space' property

pre-line This value directs user agents to collapse sequences of white space. Lines are broken at preserved newline characters, and as necessary to fill line boxes.

值得注意的是行前的值is supported in IE8+ .
