Question

我的代码绝对正常但是唯一的问题是.text()无法打破来自数据库的行，并且所有结果都在一行中，并且在对话框中已经有一些空格在我的文本之前开始。我不想使用.html()，因为它具有与我的数据库相同的所有特殊字符。

$(document).ready(function() {
    var record;

    //set up the button styling and click functionality
    $('.editButton').button({
        icons: {
            primary: "ui-icon-document"
        }
    }).click(function() {
        //set which record we're editing so we can update it later
        record = $(this).parents('.record');
        //populate the editing form within the dialog

        $('#Title').val(record.find('.sh_title').text());
        $('#Post').val(record.find('.sh_post').text());
        $('#PostId').val(record.find('.postid').text());

        //show the dialog
        $("#dialogContent").dialog("open");
    });    

    //set up the dialog box.
    $("#dialogContent").dialog({
        autoOpen: false,
        modal: true,
        buttons: {
            OK: function() {
                record.find('.sh_title').text($('#Title').val());
                record.find('.sh_post').text($('#Post').val());
                $(this).dialog("close");
            },
            Cancel: function() {
                $(this).dialog("close");
            }
        }
    });
});

当您使用html输入标记时，它是单行输入，这就是为什么它不会在文本框中显示多行，

如果您想要显示多行，然后将输入标记更改为textarea，那么它将适合您。
