javascript - 用于 Wordpress 的 PHP 计算器无法正常运行

Question

一直在努力让我的计算器工作。我使用 PHP、JS 和 CSS 对计算器进行了编码。非常基本，但是当按下计算按钮时，计算没有完成。这是我的代码。

<?php
/*
Template Name: Calculator
*/

wp_enqueue_script('calc_js', get_bloginfo('template_url').'/library/calc.js');
wp_enqueue_style('calc_css', get_bloginfo('template_url').'/library/calc.css');
get_header(); ?>

    <?php
        while ( have_posts() ) : the_post();
        ?>
        <div id="page-content-container">

            <article <?php post_class('clearfix') ?> id="post-<?php the_ID(); ?>">

                <div class="entry-content">
                    <?php the_content(); ?>

                    <div class="row-fluid" id="">
                    <div class="calc span6">

这是我的 JS 代码:

jQuery(document).ready(function() {

    jQuery('.calc .calculate').click(function() {
        var parent = jQuery(this).parents('.calc');
        parent.find('.error').removeClass('error');

        var error = false;

        var purchase = parent.find('.purchase');
        var loan = parent.find('.loan');

        var purchaseval = purchase.val();
        if (isNaN(purchaseval) || purchaseval == '') {
            error = true;
            purchase.addClass('error');
        }
        var loanval = loan.val();
        if (isNaN(loanval) || loanval == '') {
            error = true;
            loan.addClass('error');
        }

        if (error == false) {
            var perc = (loanval / purchaseval) * 100;
            parent.find('.ltv').val(perc.toPrecision(2));

            var val = loanval - (loanval * .0125);
            var val2 = loanval - val;
            parent.find('.interest').val(val2);
        }

        return false;
    });

    jQuery('.calc2 .calculate').click(function() {
        var parent = jQuery(this).parents('.calc2');
        parent.find('.error').removeClass('error');
        var error = false;

        var rent = parent.find('.rent');
        var value = parent.find('.loan');

        var rentval = rent.val();
        if (isNaN(rentval) || rentval == '') {
            error = true;
            rent.addClass('error');
        }
        var valueval = value.val();

        if (error == false) {
            var yieldval = (rentval * 12) / valueval;


            parent.find('.yield').val(yieldval * 100);

})
