Question

当我在ajax响应类“navtex-message”不起作用后使用javascript创建html时。

function formatNtxMessage( m ) {
    return '<div class="row">' +
        '<div class="col-lg-9">' +
            '<div class="navtex-message">' +
                JSON.stringify(m.content).replace(/\"/g, "")  + 
            '</div>' +
        '</div>' +          
    '</div>';
}

function format ( d ) {
    var div = $('<div/>')
     .addClass( 'loading' )
     .text( 'Učitavanje...' );

     $.ajax( {
         type: "GET",
         url: '/api/ntxMessage/' + d.id,
         success: function ( json ) {
             div
                 .html(formatNtxMessage(json.data))
                 .removeClass( 'loading' );
         }
     } );

    return div;
}

类navtex-message在文本换行中改为\ r \ n：\ n \ n

.navtex-message {
    white-space: pre-line;
}

我得到的字符串：

ZCZC QE02\r\n050640 UTC MAR\r\n\r\nSPLIT RADIO\r\n\r\nWEATHER BULLETIN FOR ADRIATIC\r\n\r\nISSUED BY THE MARINE METEOROLOGICAL CENTER SPLIT ON 05/03/2018 AT 0400 UTC\r\n\r\n1.

我做错线而不是\ r \ n？

Answer 1

JSON.stringify()将您的m.content转换为单行json。

因此对white-space: pre-line没有影响。

添加third param（空格数）以进行stringify以便漂亮打印

＆＃13;

$('pre').html(
  JSON.stringify({'a': 1, 'b': 'c'}, null, 4)
);

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<pre></pre>

＆＃13;

Answer 2

我解决了问题：

function formatNtxMessage( m ) {
return '<div class="row">' +
    '<div class="col-lg-9">' +
        '<div class="navtex-message">' +
            m.content + 
        '</div>' +
    '</div>' +          
'</div>';
}

问题是m.content是来自json的字符串值。 :) 谢谢你的帮助。

在ajax响应之后在javascript中定义类
