表单在页面加载时而不是单击时运行提交脚本

我正在尝试运行一个名为"submitScript"的脚本，当按下此表单上的提交按钮时。 submitScript 与所有其他文件位于同一目录中。这是一个很长的.js文件，与 Parse 通信（我已经在文档前面连接了 Parse ID 和机密）：

$('#submitButton').onclick = 
                        Parse.Cloud.run('importEvent', {
       eventName: 'Test Event',
       eventDate: 'May 4, 2016',
       posterTitles: 'AG1'nAG2'nAG3'nAG4',
       posterColleges: 'BIS'nENGR'nAG'nAG',
       judgeFirst: 'AG'nAG'nAG',
       judgeLast: 'AG1'nAG2'nAG3',
       judgeColleges: 'SCI'nENGR'nAG',
       judgeAssigned: '[1,4]'n[1]'n[2,3]'
       }).then(function(results) {
               // Event successfully created
               alert('success');
       }, function(error) {
               if (error.message == 'missing event name') {
                       alert('missing event name');
               }
               else if (error.message == 'eventname contains comma') {
                       alert('eventname contains comma');
               }
               else if (error.message == 'missing event date') {
                       alert('missing event date');
               }
               else if (error.message == 'missing poster titles') {
                       alert('missing poster titles');
               }
               else if (error.message == 'missing poster colleges') {
                       alert('missing poster colleges');
               }
               else if (error.message == 'missing judge firsts') {
                       alert('missing judge firsts');
               }
               else if (error.message == 'missing judge lasts') {
                       alert('missing judge lasts');
               }
               else if (error.message == 'missing judge colleges') {
                       alert('missing judge colleges');
               }
               else if (error.message == 'poster numbers are inconsistent') {
                       alert('poster numbers are inconsistent');
               }
               else if (error.message == 'judge numbers are inconsistent') {
                       alert('judge numbers are inconsistent');
               }
               else if (error.message == 'title contains comma') {
                       alert('title contains comma');
               }
               else if (error.message == 'pid invalid number of characters') {
                       alert('pid invalid number of characters');
               }
               else if (error.message == 'pid contains invalid character') {
                       alert('pid contains invalid character');
               }
               else if (error.message == 'first contains comma') {
                       alert('first contains comma');
               }
               else if (error.message == 'last contains comma') {
                       alert('last contains comma');
               }
               else if (error.message == 'jid invalid number of characters') {
                       alert('jid invalid number of characters');
               }
               else if (error.message == 'jid contains invalid character') {
                       alert('jid contains invalid character');
               }
               else if (error.message == 'invalid assignment format') {
                       alert('invalid assignment format');
               }
               else if (error.message == 'invalid assignment') {
                       alert('invalid assignment');
               }
               else {
                       // General error
                       alert('general error');
               }
});

下面是与脚本关联的 HTML 表单。它应该在按下提交按钮时运行。此脚本实际上为我最终将使用表单捕获的字段发送硬编码值（我想我会先解决下面的问题，然后再从表单字段中获取数据，然后将其发送出去）。

            <form>
                <input id="eventName" type="text" placeholder="Event Name" onfocus="this.placeholder = ''" onblur="this.placeholder = 'Event Name'">
                <input id="eventDate" type="text" placeholder="Event Date" onfocus="this.placeholder = ''" onblur="this.placeholder = 'Event Date'">
                <input id="posterTitles" type="textarea" placeholder="Poster Titles" onfocus="this.placeholder = ''" onblur="this.placeholder = 'Poster Titles'">
                <input id="posterColleges" type="textarea" placeholder="Poster Colleges" onfocus="this.placeholder = ''" onblur="this.placeholder = 'Poster Colleges'">
                <input id="judgeFirst" type="textarea" placeholder="Judge First" onfocus="this.placeholder = ''" onblur="this.placeholder = 'Judge First'">
                <input id="judgeLast" type="textarea" placeholder="Judge Last" onfocus="this.placeholder = ''" onblur="this.placeholder = 'Judge Last'">
                <input id="judgeColleges" type="textarea" placeholder="Judge Colleges" onfocus="this.placeholder = ''" onblur="this.placeholder = 'Judge Colleges'">
                <input id="judgeAssigned" type="textarea" placeholder="Judge Assigned" onfocus="this.placeholder = ''" onblur="this.placeholder = 'Judge Assigned'">
                <div id="submitButton">Submit</div>
                <script src = "submitScript.js">
                </script>
            </form>

我需要这个提交脚本.js只有在按下按钮时才触发。相反，它会在页面加载后立即触发。我以为 .onclick = ...会解决这个问题，但唉。我在这里做错了什么？谢谢！

在库方面，我通过CDN使用Foundation框架和jQuery。
