    嗨,我只想在应用程序中单击日历时显示弹出日历。以前,我的文本框中会有一个日期,可能是当前年份中的任何日期。我需要的是,如果我在文本框中的日期是2008年3月1日。我只想显示之后的下一个日期,我想禁用所有不可选的前一个日期。

    我用的剧本是这样的

     function positionInfo(object) {
    
    var p_elm = object;
    
    this.getElementLeft = getElementLeft;
    function getElementLeft() {

    if(typeof(p_elm) == "object"){
      elm = p_elm;
    } else {
      elm = document.getElementById(p_elm);
    }
    while (elm != null) {
      x+= elm.offsetLeft;
      elm = elm.offsetParent;
    }
    return parseInt(x);
    }
    
    this.getElementWidth = getElementWidth;
    function getElementWidth(){
    var elm;
    if(typeof(p_elm) == "object"){
      elm = p_elm;
    } else {
      elm = document.getElementById(p_elm);
    }
     return parseInt(elm.offsetWidth);
    }
    
      this.getElementRight = getElementRight;
      function getElementRight(){

    这似乎起作用了。不过要好好测试一下。

    由于某种原因,格式化不起作用。

    所以,我把它贴到了shortext.com上。链接如下: link text

    别再发明轮子了…看一看 jQuery UI .
