我有问题。我希望我的javascript文件能够找到用户是否选择“否”他们不想要盾牌,如果选择“Arc”则应该勾选checkbox1。同样适用于“否”和“伊利”刻度复选框4。 “No”和“Spec”也勾选checkbox7。但如果他们选择“不”和“任何”他们可以选择任何东西。我该怎么做呢。
HTML code:
<html>
<head>
<script type="text/javascript" src="myJavascript.js"></script>
</head>
<body>
<select id="likeShield" onchange="showTicks(this)">
<option value="select1">Select</option>
<option value="yesShield">Yes</option>
<option value="noShield">No</option>
</select>
<select id="chooseShield">
<option value="select1">Select</option>
<option value="arc">Arcane</option>
<option value="ely">Elysian</option>
<option value="spec">Spectral</option>
<option value="anylist">Choose any</option>
</select>
<table border = "1">
<tr>
<th> tickbox </th>
<th> shield parts </th>
<th> description </th>
<th> cost </th>
</tr>
<tr>
<td><input type="checkbox" id="cb1"></td>
<td> arc sigil </td>
<td> Large magic part </td>
<td> 5m </td>

<tr>
<td><input type="checkbox" id="cb2"></td>

<td> 40m </td>

<tr>
<td><input type="checkbox" id="cb6"></td>
<td> elysian special item </td>

<td> 4m </td>

<tr>

<td> Does double damage </td>
<td> 30m </td>

我认为它是一个IF声明,但我不知道如何实现它。
有人可以帮我解决这个问题吗?
由于
专利
编辑:
我的javascript if声明:
function showTicks(what)
{
if (what.value == ("noShield") && ("arc")) {
if (what.value == ("noShield") && ("ely")) {
if (what.value == ("noShield") && ("spec")) {
document.getElementById("cb1").checked=true;
document.getElementById("cb4").checked=true;
document.getElementById("cb7").checked=true;
}
else
document.getElementById("cb7").checked=false;
}
else
document.getElementById("cb4").checked=false;
}
else
document.getElementById("cb1").checked=false;
}

使用jQuery:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script type="text/javascript">
$("#likeShield").change(function() {
if ($("#likeShield").val() == "yesShield") {
if ($("#chooseShield").val() == "arc") {
$("#cb1").prop("checked", true);
} // etc
}
})
</script>
这会将处理程序附加到change
select的likeShield
事件,因此每当用户更改该下拉列表中的选择时,它都会运行附加函数。

我会使用jQuery。结帐working demo。
在更改事件中读取所选值,比较并设置checkox。
$(".conf").change(function() {
tickBoxes();
})
function tickBoxes() {
var likeShield = $("#likeShield").val();
var chooseShield = $("#chooseShield").val();
if (likeShield == 'noShield' && chooseShield == 'arc') {
$("#cb1").prop('checked', true);
}
}

但要实现这一点,您需要在HTML中使用表单,请参阅链接:http://jsbin.com/oyuxah/2/edit
var likeShield = document.getElementById('likeShield');
var chooseShield = document.getElementById('chooseShield');
function checkAll(){
if(likeShield.value=="noShield" && chooseShield.value=="arc"){
document.getElementById('cb1').checked =true;
document.getElementById('cb2').checked =false;
document.getElementById('cb3').checked =false;
document.getElementById('cb4').checked =false;
document.getElementById('cb5').checked =false;
document.getElementById('cb6').checked =false;
document.getElementById('cb7').checked =false;
}
if(likeShield.value=="noShield" && chooseShield.value=="ely"){
document.getElementById('cb1').checked =false;
document.getElementById('cb2').checked =false;
document.getElementById('cb3').checked =false;
document.getElementById('cb4').checked =true;
document.getElementById('cb5').checked =false;
document.getElementById('cb6').checked =false;
document.getElementById('cb7').checked =false;
}
if(likeShield.value=="noShield" && chooseShield.value=="spec"){
document.getElementById('cb1').checked =false;
document.getElementById('cb2').checked =false;
document.getElementById('cb3').checked =false;
document.getElementById('cb4').checked =false;
document.getElementById('cb5').checked =false;
document.getElementById('cb6').checked =false;
document.getElementById('cb7').checked =true;
}
if(likeShield.value=="noShield" && chooseShield.value=="anylist"){
document.getElementById('cb1').checked =false;
document.getElementById('cb2').checked =false;
document.getElementById('cb3').checked =false;
document.getElementById('cb4').checked =false;
document.getElementById('cb5').checked =false;
document.getElementById('cb6').checked =false;
document.getElementById('cb7').checked =false;
}
}

您应该创建一个能够修改/检查DOM的Javascript脚本(内联与否)。
