本文实例为大家分享了JS如何生成动态列表的具体代码,供大家参考,具体内容如下
思路: JS中写函数----HTML中利用表单元素获取用户输入的行和列的值,调用JS中的函数。
主要用到的知识有:JS就不说了,表单元素,以及其属性value,和表格…
代码:
<!doctype html> <html> <head> <meta charset = "utf-8"> <title>创建动态表格</title> <style> #form1{ padding:10px; width:400px; margin:0 auto; } </style> <script type = "text/javascript"> function createTable() { var r1 = document.getElementById( "row" ).value; var c1 = document.getElementById( "col" ).value; var n = 1; //单元格中的文字 var str = "<table width = '100%' border = '1' cellspacing = '0' cellpadding = '0' ><tbody>"; for(i = 0; i<r1; i++) { str = str+"<tr align = 'center'>" for(j = 0; j<c1; j++) str = str+"<td>"+(n++)+"</td>" str = str+"</tr>" } var d1 = document.getElementById( "d1" ); d1.innerHTML = str+"</tbody></table>"; } </script> </head> <body> <form id = "form1" name = "form1" method = "post" action = ""> <fieldset> <legend>动态创建表格</legend> 输入表格的行数:<input type = "text" id = "row" placeholder = "请输入表格的行数" required autofocus /><br/> 输入表格的列数:<input type = "text" id = "col" placeholder = "请输入表格的列数" /><br/> <input type = "button" id = "ok" value = "产生表格" onclick = "createTable()"/> </fieldset> </form> <div id = "d1"></div> </body> </html>
