方法:eval()
eg:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>将字符串作为函数名调用函数</title> </head> <body> <span>指标:</span> <select id="zhibiao"> <option selected="" value="总体">总体</option> <option value="queryManagementVolume">办理量</option> <option value="queryTimeConsuming">平均耗时</option> <option value="queryOvertimePercent">超时占比</option> </select> </body> <script src="../js/jquery.js"></script> <script> $(document).on("change",‘select#zhibiao‘,function(){ var fn=$(this).val(); /* fn(); */ eval(fn+"()"); }); function queryManagementVolume(){ console.log("查询办理量"); } function queryTimeConsuming(){ console.log("查询平均耗时"); } function queryOvertimePercent(){ console.log("查询超时占比"); } </script> </html>
var slideArr=new Array( ‘slideLeft‘, ‘slideTop‘, ‘slideRight‘, ‘slideBottom‘, ‘slideLeftTop‘, ‘slideTopRight‘, ‘slideRightBottom‘, ‘slideBottomLeft‘ ); function slideRandom(arr=slideArr,width,height,time) { var length=slideArr.length; var index=Math.floor(Math.random()*length); var functionName=slideArr[index]; //alert(functionName); eval(functionName+‘(width,height,time)‘); }
