Question

我正在处理此表单选择条件，该条件将在单击提交按钮时加载特定页面。现在我收到windows.location的意外令牌错误。所有文件都在同一个文件夹中

<script>
$(document).ready(function() {
    $("#process_app").submit(function() {
        var selrange = $("select#range").val();
        var selplace = $("select#place").val();
        var selindustry = $("select#industry").val();

        if (selrange = '1') {
            // if value 1 load US short app, if value 2 load Canada short app
            window.location = selplace = "1" ? 'application_us_short.php' : 'application_ca_short.php');
        }
        if ((selrange = '2') && (selindustry = '2' || selindustry = '10')) {
            window.location = selplace = "1" ? 'application_us_short.php' : 'application_ca_short.php');
        } 
        if ((selrange = '2') && (selindustry != '2' || selindustry != '10') || selrange = '3')  {
            window.location = selplace = "1" ? 'application_us.php' : 'application_ca.php');
        }         

    });
});
    </script>

Answer 1

您正在分配值而不是比较

selplace = "1"

试试这个

selplace == "1"

Answer 2

您正在分配值而不是检查它

您的代码

 window.location = selplace = "1" ? 'application_us_short.php' : 'application_ca_short.php');

建议的更改

 window.location = selplace === "1" ? 'application_us_short.php' : 'application_ca_short.php');

Answer 3

试试这个，然后在if语句中更改括号

$(document).ready(function() {
    $("#app_type").submit(function() {
        var selrange = $("select#range").val();
        var selplace = $("select#place").val();
        var selindustry = $("select#industry").val();
    

        if (selrange == '1') {
            // if value 1 load US short app, if value 2 load Canada short app
            window.location = selplace = "1" ? 'application_us_short.php' : 'application_ca_short.php';
        }
        if ((selrange == '2') && (selindustry == '2' || selindustry == '10')) {
            window.location = selplace = "1" ? 'application_us_short.php' : 'application_ca_short.php';
        } 
        if ((selrange == '2') && (selindustry != '2' || selindustry != '10') || (selrange = '3'))  {
            window.location = selplace = "1" ? 'application_us.php' : 'application_ca.php';
        }       
      alert(window.location);
    });
});

Answer 4

window.location无效，因为您要为selrange（selrange = '1'，selrange = '2'）分配一个值，而不是比较该值，请替换为selrange == '1' ,selrange == '2'

JQuery条件是windows.location
