【问题描述】:
因此,我将创建一个锻炼网站作为一种爱好,并且在锻炼创建者方面需要一些帮助。所以我有一个页面,我想根据一个人的限制随机创建一个锻炼。这是该部分的网页:random workout creator。基本上,当一个人选择了锻炼限制后,他们会点击“创建锻炼”按钮,然后页面会显示10张不同的锻炼图片供用户完成。所以这是我的问题:当我输入“无限制”并创建锻炼时,只显示一个图像,而不是 10 个。当我输入“怀孕”或“低影响”时,单击“创建锻炼”按钮,没有任何反应.任何人都可以查看我的 javascript 并查看我做错了什么吗?这是javascript的代码:
function createOffice(){
var randomimages=new Array();
randomimages[0]="images/office/arm circles.gif"
randomimages[1]="images/office/calf raises.gif"
randomimages[2]="images/office/chair step ups.gif"
randomimages[3]="images/office/curtsy lunge.gif"
randomimages[4]="images/office/desk pushups.gif"
randomimages[5]="images/office/lunge2.gif"
randomimages[6]="images/office/Lunges.gif"
randomimages[7]="images/office/side lunge.gif"
randomimages[8]="images/office/Squat.gif"
randomimages[9]="images/office/squat punches.gif"
randomimages[10]="images/office/Step up with knee up.gif"
randomimages[11]="images/office/tricep dips.gif"
randomimages[12]="images/office/Butt Kickers.gif"

【问题讨论】:
-
像@rla4 说的那样去掉你的
document.writes,也像@eventHandler 说的那样使用分号,但你也应该记住,这些可能会显示相同的图像。
