第二种方法
function sx(){var rntArray=[],temp,hasValue;var array=document.getElementById("neirong").value.split("
");for(var i in array){ temp=array[i]; hasValue=false; for(var j in rntArray){if(temp===rntArray[j]){ hasValue=true; break;} } if(hasValue===false){rntArray.push(temp); }}document.getElementById("neirong1").value=rntArray.join("
"); }
