JS禁用页面上所有控件的实现方法(附demo源码下载)

function DisableElements(container,blnHidenButton){  if (!container)  return;  var aEle;  if (navigator.appName =="Microsoft Internet Explorer") //IE  {    for (var i=0;i<container.all.length;i++)    {      aEle = container.all[i];      tagName = aEle.tagName.toUpperCase();      if ((tagName=="SELECT"))      {        aEle.disabled = true;        if(tagName=="BUTTON" && blnHidenButton)        {          //aEle.style.display = "none";//对button不做处理        }      }      else if (tagName=="INPUT")      {        if (aEle.type.toUpperCase()!="HIDDEN")        {          if (aEle.type.toUpperCase()=="TEXT")          {            ReadonlyText(aEle);          }          else if (aEle.type.toUpperCase()=="BUTTON")          {            //do nothing;          }          else          {            aEle.disabled = true;          }        }        if((aEle.type.toUpperCase()=="BUTTON"||aEle.type.toUpperCase()=="SUBMIT") && blnHidenButton)        {          //aEle.style.display = "none";//对button不处理        }      }      else if (tagName=="TEXTAREA")      {        ReadonlyText(aEle);      }    }  }  else//非IE浏览器  {    var aEle = container.getElementsByTagName("select");    for (var i=0;i< aEle.length;i++)    {      aEle[i].disabled = true;    }    aEle = container.getElementsByTagName("button");    for (var i=0;i< aEle.length;i++)    {      aEle[i].disabled = true;    }    aEle = container.getElementsByTagName("textarea");    for (var i=0;i< aEle.length;i++)    {      ReadonlyText(aEle[i]);    }    aEle = container.getElementsByTagName("input");    for (var i=0;i< aEle.length;i++)    {      if (aEle[i].type.toUpperCase()!="HIDDEN")      {        if (aEle[i].type.toUpperCase()=="TEXT")        {          ReadonlyText(aEle[i]);        }        else        {          aEle[i].disabled = true;        }      }      if((aEle[i].type.toUpperCase()=="BUTTON"||aEle[i].type.toUpperCase()=="SUBMIT")&&blnHidenButton)      {        aEle[i].style.display = "none";      }    }  }}function ReadonlyText(objText) {  if (objText){    //objText.style.backgroundColor = "menu";    objText.style.background = "#E6E6E6";    //objText.style.color = "black";    objText.readOnly=true;  }}
