JavaScript函数参数不起作用 [英] Javascript Function Parameters Not Working

问题描述

我读过的每个站点都说，如果声明了一个函数，它将只带有一个参数，但是我不能在这里使用它.

Every site I've read says a function would just take a parameter if you declare it, however I can't get it to work here.

像这样工作:

    <script type='text/javascript'>
    function trackSubmit() { 
        setTimeout(function(){
            ga('send', 'event', 'category', 'action', 'link', 4);
        }, 100);
     }
</script>

并且:

<form onsubmit="trackSubmit()">

但是，如果我尝试这样的操作，它将无法正常工作.

However, if I try something like this, it doesn't work.

    <script type='text/javascript'>
    function trackSubmit(category, action, link) { 
        setTimeout(function(){
            ga('send', 'event', category, action, link, 4);
        }, 100);
     }
</script>

<form onsubmit="trackSubmit(testcategory, testaction, testlink)">

我该怎么做才能解决此问题?还是应该只具有多个功能，例如trackSubmit1，trackSubmit2等?虽然那不是很方便.

What can I do to fix this? Or should I just have multiple functions like trackSubmit1, trackSubmit2, etc? Though that wouldn't be very convenient.

谢谢您的帮助.

推荐答案

您需要使用qoutation <form onsubmit="trackSubmit('testcategory', 'testaction', 'testlink')"> 如果有变量，则需要像\''+ testcategory +'\'那样串联...

you need to use qoutation <form onsubmit="trackSubmit('testcategory', 'testaction', 'testlink')"> if there are variable then need to concatenate like \''+testcategory+'\' , ...
