似乎javascript函数永远不会执行.谁能告诉我为什么？

<form>
    <select type="text" name="month" id="month">
        <option value="01">January</option>
        <option value="02">February</option>
        <option value="03">March</option>
        <option value="04">April</option>
        <option value="05">May</option>
        <option value="06">June</option>
        <option value="07">July</option>
        <option value="08">August</option>
        <option value="09">September</option>
        <option value="10">October</option>
        <option value="11">November</option>
        <option value="12">December</option>
    </select>
    <button type="submit" id="jobmonth">View all job requests in this month</button>
    </form>

    <script type="text/javascript">
         $('#jobmonth').click(function() {
              console.log("work");
              var month = $('#month').val();
              console.log(month);
    }
    </script>

console.log都没有工作.PS-抱歉这个愚蠢的问题.我只是JS的初学者.

我遇到了这段代码.从输出时,除以2,但语法不熟悉我,我可以推断,其余阵列存储阵列数量的剩余部分.

#include <iostream>
#include <functional>
#include <algorithm>

using namespace std;

int main ( )
{

    int numbers[ ] = {1, 2, 3};

    int remainders[3];

    transform ( numbers, numbers + 3, remainders, bind2nd(modulus<int>( ), 2) );

    for (int i = 0; i < 3; i++)
    {
        cout << (remainders[i] == 1 ? "odd" : "even") << "\n";
    }
    return 0;

}

变换和bind2nd在这种情况下做了什么？我阅读了文档,但我不清楚.
