使用JavaScript中的变量创建通过按钮的网址 [英] Javascript using variables to create a url through buttons

问题描述

我在我的网站上点击该按钮时产生一个字。这个词，然后在一个URL呼叫用于下载一个具体的文件。

I have a button on my website that when clicked generates a word. This word is then used in a url call to download a specific file.

 <button class="button1" onclick="myFunction()">cafe</button>
 var cafe = [];
 function myFunction() {
 cafe.push('cafenew');

第二张code以下需要被推入VAR网吧词cafenew（当按钮被点击）并将其插入到URL地址：

The 2nd piece of code below takes the word 'cafenew' that was pushed into the var cafe (when the button was clicked) and inserts it into the url address:

 name=cafe

 var src = "https://www.dropbox.com/s/"+name+".kml?dl=1";

但出于某种原因，这是行不通的。加载该文件是一个层到网络地图。我检查了URL地址，一切是正确的。我用这个测试：

But for some reason this does not work. The file being loaded is a layer onto a web map. I have checked the url address, everything is correct. I tested this by using:

 var cafe = "cafenew" 

和图层加载正确的，但我明显松动的按钮的功能，如果我解决这个变量等于什么。

and the layer loaded correctly, but I obviously loose the function of the button if I fix what the variable equals.

在此先感谢您的帮助！

Thanks in advance for any help!

推荐答案

试试这个它的正常工作：

HTML：

<button class="button1" onclick="myFunction();">cafe</button>

脚本：

 var cafe = [];
 window.myFunction = function() {
 cafe.push('cafenew');
 console.log(cafe);
 var name = cafe[0];
 var src = "https://www.dropbox.com/s/"+name+".kml?dl=1";
 console.log(src);
 }
