Javascript生成的表格不显示

Question

此表未显示在我的 html 文件中：任何人都可以看到明显的错误吗？我已经盯着它看了好几个小时了！

<div id="data_list">
            <script type="text/javascript">
    document.write("<table border='1' rules='rows' cellspacing='0'>")
    document.write("<tr>");
    document.write("<th>Date</th><th>Amount</th><th>First Name</th>");
    document.write("<th>Last Name</th><th>Address</th>");
    document.write("</tr>");

    for (i=0;i<=amount.length;i++){
        if (i%2=0){
            document.write(<tr>);
            }else{
            document.write("<tr class='yellowrow'>");
            }

        document.write("<td>" + date[i] + "</td class='amt'>" + amount[i]+ "</td>");
        document.write("<td>" +firstName[i] + "</td><td>" + lastName[i] + "</td>");
        document.write("<td>" + street[i] + "<br />" + city[i] + ", " +state[i]+ "" +  zip[i] + "</td>");
        document.write("</tr>");
}
    document.write("</table>");
    </script>

Answer 1

这里：

if (i%2=0){
    document.write(<tr>);
}else{
    document.write("<tr class='yellowrow'>");
}

应该是

if (i%2==0){
    document.write('<tr>');
}else{
    document.write("<tr class='yellowrow'>");
}

i%2=0 应该是i%2==0 另外，<tr> 应该是一个字符串'<tr>'
