用html+javascript打造公文一键排版系统3：获取参数设置、公文标题排版 -阿里云开发者社区

我们用自定义函数setDocFmt()来实现对公文的排版。

一、获取公文参数值

要对公文进行排版，首先要读取公文“参数设置”区中的参数值。比如公文要求对公文标题的一般规定是：一般用2号小标宋体字，居中显示。标题与正文中间空一行。

这些是“参数设置”中关于“文件标题”的默认设置。如果用户有特殊的要求，也可以在“参数设置”修改默认的设置。

所以我们在setDocFmt()中首先使用调用自定义函数getArg()来获取这些参数。

function getArg()
{
  taDbg.value += "\n--- getArg()" ;

  //标题字体名 font name
  dtfn = document.getElementById('selDocTitleFontName').value;
  //alert(fn);
  //标题字号 font size
  dtfs = document.getElementById('selDocTitleFontSize').value;
  //alert(fs);
  //标题对齐方式 text align
  dtta = document.getElementById('selDocTitleAlign').value;

  //一级标题字号 font name
  pt1fn = document.getElementById('selPrimaryTitleFontName').value;
  //一级标题字号 font size
  pt1fs = document.getElementById('selPrimaryTitleFontSize').value;

  //二级标题字号 font name
  pt2fn = document.getElementById('selSecondaryTitleFontName').value;
  //二级标题字号 font size
  pt2fs = document.getElementById('selSecondaryTitleFontSize').value;

  //正文字体名称
  mtfn = document.getElementById('selMainTextFontName').value;
  //正文字体字号
  mtfs = document.getElementById('selMainTextFontSize').value;
  //行距 row spacing
  rs  = document.getElementById('tbRowSp').value;
  //首行行首空格数
  sn  = document.getElementById('tbLeadSpNum').value;
}

二、公文标题排版

在获取公文参数值后，我们正式开始排版。

与“清除格式”一样，我们首先调用getClearInfoArray() 对要排版的内容进行格式清除。

然后在开始对公文标题进行排版，这主要在自定义函数setDocTitle()中完成：

function setDocTitle(s)
{
    taDbg.value += "\n--- setDocTitle("+ s  + ");" ;
    
    return '<p style="font-family:' + dtfn + ';font-size:' + dtfs +'pt; text-align:' + dtta + '; line-height:' +  rs + 'pt;">' + s;
}

主要是使用<p>标签，并通过css把与标题相关的参数值作为<p>的属性。

由于标题通常与正文中间空一行，所以setDocFmt()中在setDocTitle()完成标题格式设置后，我们添加了“<p style="line-height:"' + rs +'"> ';”来实现。即：

//标题
  t[0]  = setDocTitle(t[0]) + '</p><p style="line-height:"' + rs +'"> ';

这样我们就完成了标题的排版。这里我们不考虑标题有几行的情况。

function setDocFmt()
{
  taDbg.value += "\n---setDocFmt()\n";

  getArg();

  var t = getClearInfoArray();

  //标题
  t[0]  = setDocTitle(t[0]) + '</p><p style="line-height:"' + rs +'"> ';

  /*处理正文*/  

  edRichBody.innerHTML = t.join('</p><p>'); 
}

效果如下图：
