如何拆分逗号分隔的字符串并使用javascript插入到html中

时间:2015-01-20 06:31:55

标签: javascript jquery html

这是字符串:

var numbers = "1,2,3,4,5,6,7,8,9,10";

我希望将此字符串分开并插入到html中。

每次刷新页面时,数字应逐个迭代。

编辑:抱歉,忽略上面这一行。如果我点击了一个按钮,它应该遍历字符串并逐个显示。

任何人都可以帮我这么做吗?

参考这个小提琴:

http://jsfiddle.net/e1ky6rtj/

单击按钮:

<button onclick='clicked()'>ClickMe</button>

function clicked(){
var numbers = "1,2,3,4,5,6,7,8,9,10";
var c= numbers.split(','); //Split a string into an array of strings
for(var i=0;i<c.length;i++)
    alert(c[i]);
}

试试这个,

var numbers = "1,2,3,4,5,6,7,8,9,10";
var n=numbers.split(','),
    i=0;
$('#button').on('click', function(){
   $('#show').text(n[i++]);
   if(i==n.length) i=0;
});

<强> HTML

<div id="show"></div>
<button id="button">Increment me</button>

   var numbers = "1,2,3,4,5,6,7,8,9,10";
   var n = numbers.split(','),
     i = 0;
   $('#button').on('click', function() {
     $('#show').text(n[i++]);
     if(i==n.length) i=0;
   });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="show"></div>
<button id="button">Increment me</button>

如果你想要它在画布上,那就试试吧,

<强> Jquery的

var numbers = "1,2,3,4,5,6,7,8,9,10";
var n=numbers.split(','),
    i=0;
var canvas=document.getElementById("myCanvas");
var ctx=canvas.getContext("2d");

ctx.font="18px Arial";
$('#button').on('click', function(){
    ctx.clearRect(0,0,300,300);
    ctx.fillText(n[i++],20,20);    
});

<强> HTML

<canvas id="myCanvas" width="200" height="100"
style="border:1px solid #000000;">
Your browser does not support the HTML5 canvas tag.
</canvas>
<button id="button">Increment me</button>

希望,这有帮助,

var indexLetter=0;
function paintletter(retryletter) {
    var chars = charscontainer.innerHTML.split('');

     // comment the blow code
     /*letter = retryletter ||
             chars[parseInt(Math.random() * chars.length,10)]; */
     // add the below code
      letter = retryletter ||
             chars[indexLetter++];
      if(indexLetter==chars.length) indexLetter=0;
      c.width = container.offsetWidth;
      ......

HTML:

<div id="x"></div>
<button id="y">---</button>

JS:

var numbers = "1,2,3,4,5,6,7,8,9,10";

$('#y').click(function () {
    numbers.split(",").forEach(function(n, i) {
        console.log(n + ' ' + i);
        setTimeout(function() {
            $('<p>').text(n).appendTo('#x');
        }, i * 200);
    });
});

您可以使用默认功能

p,

var array = numbers.split(",");

数组将是一个普通的javascript数组

var numbers = "1,2,3,4,5,6,7,8,9,10";
$(numbers.split(',')).each(function(){

使用.split(',')这将返回按,

分割的数据数组

var numbers =&#34; 1,2,3,4,5,6,7,8,9,10&#34 ;;

$("button").on('click', function () {
    var spltValue = String(numbers).split(",");
    for (var i = 0; i < spltValue.length; i++) {
        var aData = spltValue[i];
        console.log(aData);
    }
});

var numbers = "1,2,3,4,5,6,7,8,9,10";
var dataArray = numbers.split(",");

推送到数组并相应地处理它。
