要创建一个包含代码示例的“步骤向导表单”,可以按照以下步骤进行操作:
标签来创建表单。
.step {
display: none;
}
.step:first-child {
display: block;
}
// 获取表单和所有步骤
const form = document.getElementById('wizard-form');
const steps = Array.from(document.getElementsByClassName('step'));
// 显示下一个步骤
function showNextStep(currentStep) {
const currentIndex = steps.indexOf(currentStep);
currentStep.style.display = 'none';
steps[currentIndex + 1].style.display = 'block';
}
// 显示上一个步骤
function showPreviousStep(currentStep) {
const currentIndex = steps.indexOf(currentStep);
currentStep.style.display = 'none';
steps[currentIndex - 1].style.display = 'block';
}
// 监听下一步按钮的点击事件
document.getElementById('next-1').addEventListener('click', function() {
const currentStep = document.getElementById('step-1');
if (form.checkValidity()) {
showNextStep(currentStep);
} else {
form.reportValidity();
}
});
document.getElementById('next-2').addEventListener('click', function() {
const currentStep = document.getElementById('step-2');
if (form.checkValidity()) {
showNextStep(currentStep);
} else {
form.reportValidity();
}
});
// 监听上一步按钮的点击事件
document.getElementById('prev-2').addEventListener('click', function() {
const currentStep = document.getElementById('step-2');
showPreviousStep(currentStep);
});
document.getElementById('prev-3').addEventListener('click', function() {
const currentStep = document.getElementById('step-3');
showPreviousStep(currentStep);
});
// 监听表单提交事件
form.addEventListener('submit', function(event) {
event.preventDefault();
if (form.checkValidity()) {
// 执行表单提交操作
} else {
form.reportValidity();
}
});
通过按照上述步骤,你就可以创建一个包含代码示例的“步骤向导表单”。用户可以按照步骤逐步填写表单,并在每个步骤之间进行导航。同时,表单也会进行验证,确保用户输入的数据符合要求。
