我要做的是获取输入到文本区域的用户信息,根据某人的程度显示为消息。因此,如果我选中BA的方框,则光标会聚焦在BA文本区域,具体取决于我输入的内容:让我们说:科学,消息将显示为firstName +"您拥有以下学位:
BA在科学。"或者如果我在MA文本区域上选中MA复选框和光标.focus(es)并输入Business,则它将显示为" firstName +"你拥有以下学位:。商业硕士。"等任何帮助表示赞赏。
HTML CODE:
<div id="mycbxs">
<br><strong> </strong>
<br><input type="checkbox" id="BAcbx" value="B"> BA
<br><input type="checkbox" id="MAcbx" value="M"> MA
<br><input type="checkbox" id="PHDcbx" value="P"> PHD
</div>
<div id="myinputs">
<br><strong>Discipline</strong>
<br><input type="text" id="BAText" size="30">
<br><input type="text" id="MAText" size="30">
<br><input type="text" id="PHDText" size="30">
<br><br>
<input type="button" id="myclick" value="Submit Degree Info">
<br>
<p id="message"></p>
</div>
jQuery CODE:
$(document).ready(function(){
$("#myclick").click(function(){
var myFirst = $("#first_name").val().trim();
$("#first_name").val(myFirst);
var myMessage = myFirst + "." + " You have yet to earn any degrees.";
if(!myFirst)
{
$("#message").text() = "";
}
else
{
$("#message").text(myMessage);
}
});
$("input[type='checkbox']").click(function(){
var radioButtonsChecked = $("#mycbxs input[type ='checkbox']:checked").val();
$("#myinputs input[type ='text']").val();
if(radioButtonsChecked == "B")
{
$("#BAText").focus();
}
if(radioButtonsChecked == "M")
{
$("#MAText").focus();
}
if(radioButtonsChecked == "P")
{
$("#PHDText").focus();
}
});
$("#myclick").click(function(){
var myFirst = $("#first_name").val().trim();
$("#first_name").val(myFirst);
$("#myinputs input[type ='text']").val();
var myDegree = '';
var radioButtonsChecked = $("#mycbxs input[type ='checkbox']:checked").val();
var myMessage = myFirst + "." + " You have yet to earn any degrees.";
if(!myFirst)
{
$("#message").text() = "";
}
else
{
$("#message").text(myMessage);
}
if(radioButtonsChecked == "B")
{
myDegree = $("#BAText").val();
}
if(radioButtonsChecked == "M")
{
myDegree = $("#MAText").val();
}
if(radioButtonsChecked == "P")
{
myDegree = $("#PHDText").val();
}
var myMsg = myFirst + " You have the following degrees:" + "<br>" + "<br>" + myDegree;
$("#message").html(myMsg);
});
});

一些问题:
$("#message").text("");
语法无效。它应该是`
input[type ='text']:checked
;也许是你问题中的拼写错误text
与任何内容都不匹配,因为无法检查$(document).ready(function(){
var degree = { B: $("#BAText"), M: $("#MAText"), P: $("#PHDText") };
$("#mycbxs input[type='checkbox']").click(function(){
if ($(this).is(":checked")) degree[$(this).val()].focus();
});
$("#myclick").click(function(){
var myFirst = $("#first_name").val().trim();
$("#first_name").val(myFirst);
var $checked = $("#mycbxs input[type='checkbox']:checked");
var myDegrees = $checked.map(function () {
return $(this).attr("name");
}).get().concat($checked.map(function () {
return degree[$(this).val()].val();
}).get()).join(', ');
var myMsg = !myFirst ? "Please enter your name."
: myDegrees ? myFirst + ". You have the following degrees: " + myDegrees
: myFirst + ". You have yet to earn any degrees.";
$("#message").text(myMsg);
});
});
输入元素。有些事情也可以用更有效和简洁的方式编写:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="first_name" value="John">
<div id="mycbxs">
<input type="checkbox" id="BAcbx" value="B" name="BA"> BA
<br><input type="checkbox" id="MAcbx" value="M" name="MA"> MA
<br><input type="checkbox" id="PHDcbx" value="P" name="PHD"> PHD
</div>
<div id="myinputs">
<strong>Discipline</strong>
<br><input type="text" id="BAText" size="30">
<br><input type="text" id="MAText" size="30">
<br><input type="text" id="PHDText" size="30">
<br>
<input type="button" id="myclick" value="Submit Degree Info">
<span id="message"></span>
</div>
