我正在创建一个网站上,用户输入数据,然后它被提交到一个数据库,同时用户收到一封邮件。
<body>
<form method="post" action="">
<input id="input-3" name="change" type="text" placeholder="CHG000010333653" required autofocus style="text-transform:uppercase" pattern=^CHG[0-9]{12,12}$ title="The format should be in CHG000010333653 "/>

</label>
<button type="submit">Submit Details</button>
<p class="tip">Press Tab</p>
<div class="signup-button">Begin</div>
</form>
<script>因此,如果input-4、input-5和input-14的input -4、input -5和input-7都不是"Yes“,那么我想要添加额外的输入(用于注释的文本输入)。我正在为UI使用CSS (这就是为什么由于设计的原因,我在将其更改为复选框/下拉菜单时犹豫不决),该网站是使用IIS部署的。
那么有没有办法做到这一点呢?Submit按钮将数据提交到MS Access文件。
根据我的搜索,它可以(可能)通过JS完成,但我没有太多的经验,所以任何指南/帮助都将不胜感激。
Edit1:代码https://codepen.io/shwetanshu/pen/XgBLwW我的目标是,如果前4个输入域中有任何"yes“,那么第五个输入域应该是注释。否则就不会了。

您可以使用document.appendChild
var node = document.createElement("INPUT"); // Create a texte input node
var textnode = document.createTextNode("Water"); // Create a text node
node.appendChild(textnode); //Append the text to <li>
document.getElementById("myList").appendChild(node); // Append the text input to <ul> with id="myList"在这里,您可以在使用document.createElement("INPUT")创建文档之后向文档中添加一个javascript对象。您可以参考w3schools的文档。
您的代码可能如下所示:
function addTextField() {
var input_4 = document.getElementById("input-4");
var input_5 = document.getElementById("input-5");
var input_7 = document.getElementById("input-7");
var input_8 = document.getElementById("input-8");
var input_9 = document.getElementById("input-9");
var input_10 = document.getElementById("input-10");
var input_11 = document.getElementById("input-11");
var input_12 = document.getElementById("input-12");
var input_13 = document.getElementById("input-13");
var input_14 = document.getElementById("input-14");
if (/*YourCheck*/) {
var node = document.createElement("INPUT"); // Create a texte input node
var textnode = document.createTextNode("Water"); // Create a text node
node.appendChild(textnode); //Append the text to <li>
document.getElementById (/*A ID for your form*/).appendChild(node); // Append the text input to <ul> with a id for your form.
}
}注释您可以在代码中添加所需测试。您还必须向表单添加ID,然后将其放入代码中。
如果你有更多的问题请告诉我。

您可以使用javascript来尝试这样的操作:https://jsfiddle.net/yqf5nf6h/3/
如果复选框已选中或未选中,则只需隐藏和显示元素。
// listen for click
input.addEventListener("click", function(e) {
// if comment is hidden we show otherwise we hide
if (comment.style.display === 'none') {
comment.style.display = 'inline';
}else{
comment.style.display = 'none';
}});希望这能有所帮助
