FCKEditor部分常用JS功能


// JScript 文件
  
//预览
function preview() {
oFCKeditor.Value=FCKeditorAPI.GetInstance('FCKeditor1').GetXHTML(true);
FCKeditorAPI.GetInstance('FCKeditor1').Preview();
}
//源代码/编辑转换
function viewsrc()
{
var obj=FCKeditorAPI.GetInstance('FCKeditor1');
oFCKeditor.Value=obj.GetXHTML(true);
obj.SwitchEditMode(FCK_EDITMODE_SOURCE);
if(obj.EditMode==FCK_EDITMODE_SOURCE)
{
document.getElementById("btn_src").value="编辑";
document.getElementById("btn_src").title="以所见即所得模块编辑";
}
else
{
document.getElementById("btn_src").value="源代码";
document.getElementById("btn_src").title="以源代码模块编辑";
}
  
}
//增加编辑区大小
function upsize()
{
  var height=oFCKeditor.Height;
  if(height<1200)
  {
    oFCKeditor.Height=oFCKeditor.Height+200;
    document.getElementById("FCKeditor1___Frame").height=oFCKeditor.Height;
  } 
  if(oFCKeditor.Height>1000)
    document.getElementById("btn_upsize").disabled="disabled";
  document.getElementById("btn_downsize").disabled="";    
}
//减小编辑区大小
function downsize()
{
  var height=oFCKeditor.Height;
  if(height>200)
  {
    oFCKeditor.Height=oFCKeditor.Height-200;
    document.getElementById("FCKeditor1___Frame").height=oFCKeditor.Height;
  }
  if(oFCKeditor.Height<400)
    document.getElementById("btn_downsize").disabled="disabled";
  document.getElementById("btn_upsize").disabled="";
  
}
//去除字符串首尾空格
String.prototype.trim = function()

    // 用正则表达式将前后空格
    // 用空字符串替代。
    return this.replace(/(^s*)|(s*$)/g, "");
}
//重置编辑器(清空)
function resetFCKEditor()
{
FCKeditorAPI.GetInstance('FCKeditor1').SetHTML("");
}
//插入HTML代码到当前位置
function inserthtml()
{
  var htmlstr=document.getElementById("insertstr").value;
  if(htmlstr.length>2)
  {
    FCKeditorAPI.GetInstance('FCKeditor1').InsertHtml(htmlstr);
  }
  document.getElementById("insertstr").value="";
