首先,我很抱歉,如果这是一个很长的代码段,但是,我正在尝试创建一个模态窗口,用于写入您在用户表单中写入的内容,并要求您确认。我目前正在上课,学习Javascript,我不允许使用innerHTML,我必须动态编写“Firstname:”等(firstname的文本),不允许在弹出窗口中编写它。我已经得到了大部分工作但是“名字:”“姓氏”等出现为“未定义”或(正如你可以看到我在这种情况下只用名字尝试的东西)出现为“null”。
希望有人可以为我阐明这个主题,这是HTML:
<form action="http://voyager.lnu.se/tekinet/kurser/dtt/wp_webbteknik/process_form.php" method="POST" id="userform" target="_blank">
<p id="formQuestion1">Förnamn</p>
<div id="error1"></div>
<input type="text" name="firstName" id="test"/>
<p id="formQuestion2">Efternamn</p>
<div id="error2"></div>
<input type="text" name="lastName" />
<p id="formQuestion3">Postnummer</p>
<div id="error3"></div>
<input type="text" name="postCode" id="codeText"/>
<p id="formQuestion4">E-post</p>
<div id="error4"></div>
<input type="text" name="eMail" />
<br />
<br />
<label id="model" class="formQuestion" for="priceModel">Prismodell</label>
<br />
<select name="Type" id="priceModel">
<option value="Låg" selected>Låg</option>
<option value="Medel">Medel</option>
<option value="Hög">Hög</option>
</select>
<br />
<br />
<br />
<input id="sendButton" type="submit" value="Genomför Köp" />
</form>
这是模态窗口(Javascript)的片段
function popup(backgroundDiv) {
var popForm = document.getElementById("userform");
var myDiv = document.createElement("div");
myDiv.className = "popupWindow";
var priceModel = document.getElementById("priceModel");
// Knappar
var newButton = document.createElement("button");
var newerButton = document.createElement("button");
newButton.setAttribute("value", "Skicka");
newButton.innerHTML = "Skicka"; // Here I actually use innerHTML because I don't know
newerButton.innerHTML = "Stäng"; // any other way to set the text inside the button
newButton.className = "popupButton";
newerButton.className = "popupButton";
newButton.setAttribute("id", "Skicka");
newerButton.setAttribute("id", "Avbryt");
myDiv.appendChild(newButton);
myDiv.appendChild(newerButton);
// Information
var h1 = document.createElement("h1");
h1.setAttribute("id", "popuph1");
var h1Text = document.createTextNode("Vänligen kontrollera dina uppgifter");
var text = document.getElementById("formQuestion1");
var writeFname = text.nodeValue + popForm.elements.firstName.value;
var writeLname = document.getElementById("formQuestion2").value + popForm.elements.lastName.value;
var writeCode = document.getElementById("formQuestion3").value + popForm.elements.postCode.value;
var writeMail = document.getElementById("formQuestion4").value + popForm.elements.eMail.value;
var writePlan = document.getElementById("model").value + priceModel.value;
var p1 = document.createTextNode(writeFname);
var p2 = document.createTextNode(writeLname);
var p3 = document.createTextNode(writeCode);
var p4 = document.createTextNode(writeMail);
var p5 = document.createTextNode(writePlan);
h1.appendChild(h1Text);
myDiv.appendChild(h1);
myDiv.appendChild(p1);
myDiv.appendChild(document.createElement('br'));
myDiv.appendChild(p2);
myDiv.appendChild(document.createElement('br'));
myDiv.appendChild(p3);
myDiv.appendChild(document.createElement('br'));
myDiv.appendChild(p4);
myDiv.appendChild(document.createElement('br'));
myDiv.appendChild(p5);
document.body.appendChild(myDiv);
newButton.onclick = function () {
document.body.removeChild(myDiv);
document.body.removeChild(backgroundDiv);
return true;
};
答案 0 :(得分:1)
如果您不想使用innerHTML,那么您可以使用这些选项,假设您想要来自此节点的值<p id="formQuestion1">Förnamn</p>
然后你的代码将是
var dom = document.getElementById('formQuestion1');
1) var res = dom.innerText;
OR
2) var res = dom.textContent;
OR
3) var res = dom.firstChild.nodeValue;
