jquery循环获取table中input的值,要求一行一行的读取组织成字符串 求代码

<script type="text/javascript">function send(){ var tableArr = []; //存所有数据百 $("table tr:not(:first)").each(function(){ //便利除标题行外所有行 var trArr = []; //存行数度据 $("input,select",this).each(function(){ //便利行内的input select的值 trArr.push($(this).val()); }); tableArr.push(trArr.join()); //行数据格式 }); var value = tableArr.join(";"); //向后台传入的值,行回与行之间“;”隔开 $.post("后台地址答",{value:value},function(data){ //回调函数 });}</script>

java 有没有直接把ascii数组转字符串的方法?循环转的就不要回我了。转换例子如下:

@Testpublicvoidtest(){e68a84e8a2ad7a6431333335346138char[]testChar={32,32,32,32,32,32,32,32,32,32,50,48,49,52,49,50,50,52,50,48,48,48,49,52,48,48,48,32,32,32,32,32,32,32,32,32,32,32,67,65,75,45,48,49,65,76,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,50,48,49,52,49,50,50,52,50,48,48,48,49,52,56,55,50,48,48,32,32,48,48,48,48,48,48,48,48,72,65,76,65,82,77,32,84,69,88,84,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32,32};StringtestStr=String.valueOf(testChar);System.out.println("-->"+testStr+"<--");}

用JS编写函数rightchange(char,n) 实现字符串char循环右移n位。rightchange("abcdefg",2) 返回"fgabcde"

&#百65279;&#度知65279;<script type="text/javascript">function rightchange(char,n){return char.substr(char.length-n)+char.substr(0,char.length-n-1);}//演示用道alert(rightchange("abcdefg",2));</script>

js如何将循环出的两种值按顺序放入字符串中

varee=document.getElementById("text_").value;ss=ee.split(",");varzz=[];//创建知过道渡数版组权for(vari=0;i<ee.length;i++)zz.append(ee[i]==""?"aa":ee[i]);varstr=zz.join(",");alert(str);

js中如何获取字符串的后四位

var str= "abcdefg";alert(str.substr(str.length-4));本回答被网友采纳
