javascript - mootools html 和 css 操作帮助

Question

我有以下 HTML

<div class="goto_step3">
<a href="<?= $this->sitePfx ?>/cart/paypal/" id="js_checkout_now" class="arrow">Checkout &amp; Pay</a>
<? if($this->discountCodeErrorMessage): ?>
    <p class="error discountError"><?= $this->discountCodeErrorMessage ?></p>
<? endif; ?>
<div class="discountCode fncFixedHeight <?= $this->has_discount ? 'redeemed': ''; ?>">
<? if(!$this->has_discount): ?>
    <label for="inptdiscountcode">Enter discount code</label>
    <input class='fncInpDiscountCode' id="inptdiscountcode" type="text" name="discount_code" value="" />
<? else: ?>
    <? if(!(empty($this->discount['discount_message']))): ?>
    <?= $this->discount['discount_message']; ?>
    <? else: ?>
    Voucher code redeemed
    <? endif; ?>
<? endif; ?>

在 DomReady 上，我希望制作 mootools ，.discountCode display:none并且.goto_step3 p display:none在单击我希望display:none成为的链接时display:block

任何帮助都会很棒

Answer 1

这应该隐藏 dom 就绪的元素，并在单击链接时使它们可见。

window.addEvent('domready', function() {

    // you can pass multiple selectors to $$ each separated with a comma
    $$('.discountCode, .goto_step3 p').setStyle('display', 'none');

    $$('.goto_step3 a').addEvent('click', function() {
        $$('.discountCode, .goto_step3 p').setStyle('display', 'block');
    });

});
