问题描述
我在 jQuery 中有这样的代码:(文件名是javascript.js ...我之前使用的是JavaScript）
I have this code in jQuery: (the file name is javascript.js ...I was using JavaScript before...)
$(document).ready(function() { $("#readFile").click(function() { $.get('test.txt', function(data) { $("#bottom_pane_options").html(data); // #bottom_pane_options is the div I want the data to go }, 'text'); }); });...在HTML中：
...and this in HTML:
<!DOCTYPE html> <html> <head> <title>Culminating</title> <link href="style.css" rel="stylesheet" type="text/css"> <script type="text/javascript" src="./javascript.js"></script> <script src="maps.googleapis/maps/api/js?key=AIzaSyCJnj2nWoM86eU8Bq2G4lSNz3udIkZT4YY&sensor=false"> </script> <script src="ajax.googleapis/ajax/libs/jquery/2.0.0/jquery.min.js"></script> <script> function initialize() { var mapProp = { center:new google.maps.LatLng(50.569283,-84.378433), zoom:5, mapTypeId:google.maps.MapTypeId.TERRAIN }; var map=new google.maps.Map(document.getElementById("googleMap"),mapProp); } google.maps.event.addDomListener(window, 'load', initialize); </script> </head> <body> <div class="content"> <div id="googleMap"></div> <div id="right_pane_results">hi</div> <div id="bottom_pane_options"> <button id="readFile">Read File</button> </div> </div> </body>
当我检查控制台时，我得到了 Uncaught ReferenceError ，说在第一行没有定义 $ 。我假设它是指第一行的第一个字符。我从一个网站得到这个代码，我是 jquery 的新手，所以我不确定这里出了什么问题。
When I check the console, I get the Uncaught ReferenceError saying that $ is not defined on the first line. I'm assuming that it is referring to the first character on the first line. I got this code from a website and I'm new to jQuery so I'm not sure what is going wrong here.
有什么建议？
推荐答案您的脚本（首先是jQuery）：
Change the order you're including your scripts (jQuery first):
<script src="ajax.googleapis/ajax/libs/jquery/2.0.0/jquery.min.js"></script> <script type="text/javascript" src="./javascript.js"></script> <script src="maps.googleapis/maps/api/js?key=YOUR_APIKEY&sensor=false"> </script>更多推荐
