根据 jQuery 中单选按钮选择的数量显示/隐藏 1-5 个输入框,需要清理
我已经编写了一些可以完美运行的代码,但它确实是丑陋的代码,我想学习清理它。
有没有人有比这个方法更好的建议?我使用了一些属性选择器来减少重复,但我仍然需要为每个硬件分配一个巨大的块(现在有 4 个)。我想我可以使用带有硬件变量的循环吗?
$('input[name="hwA-qty"]').click(function(){
var selected = $(this).val();
if (selected == 1) { //Hide inputs 2-5
$('fieldset[id^="hwA"]').hide();
}
if (selected == 2) { //Show inputs 1 & 2
$('fieldset#hwA-2').show();
$('fieldset#hwA-3').hide();
$('fieldset#hwA-4').hide();
$('fieldset#hwA-5').hide();
}
if (selected == 3) { //Show inputs 1-3
$('fieldset#hwA-2').show();
$('fieldset#hwA-3').show();
$('fieldset#hwA-4').hide();
$('fieldset#hwA-5').hide();
}
if (selected == 4) { //Show inputs 1-4
$('fieldset#hwA-2').show();
$('fieldset#hwA-3').show();
$('fieldset#hwA-4').show();
$('fieldset#hwA-5').hide();
}
if (selected == 5) { //Show all inputs
$('fieldset[id^="hwA"]').show();
}
});
$('input[name="hwB-qty"]').click(function(){
var selected = $(this).val();
if (selected == 1) {
$('fieldset[id^="hwB"]').hide();
}
if (selected == 2) {
$('fieldset#hwB-2').show();
$('fieldset#hwB-3').hide();
$('fieldset#hwB-4').hide();
$('fieldset#hwB-5').hide();
}
if (selected == 3) {
$('fieldset#hdPvr2').show();
$('fieldset#hdPvr3').show();
$('fieldset#hdPvr4').hide();
$('fieldset#hdPvr5').hide();
}
if (selected == 4) {
$('fieldset#hdPvr2').show();
$('fieldset#hdPvr3').show();
$('fieldset#hdPvr4').show();
$('fieldset#hdPvr5').hide();
}
if (selected == 5) {
$('fieldset[id^="sdPvr"]').show();
}
}); [...]
这是 HTML:
[...]
<div class="hardwareValidation">
<div class="select">
<label for="hwA-qty">Quantity</label><br />
<label>1 <input type="radio" name="hwA-qty" value="1" checked /></label>
<label>2 <input type="radio" name="hwA-qty" value="2" /></label>
<label>3 <input type="radio" name="hwA-qty" value="3" /></label>
<label>4 <input type="radio" name="hwA-qty" value="4" /></label>
<label>5 <input type="radio" name="hwA-qty" value="5" /></label>
</div>
<fieldset id="hwA-1">
<div class="input">
<label for="hwA-1-serial">#1 - Box Serial Number</label><br />
<input type="text" name="hwA-1-serial" id="hwA-1-serial" />
</div>
<div class="checkbox">
<label>
<input type="checkbox" name="hwA-1-override" value=""> Override Validation
</label>
</div>
</fieldset>
<fieldset id="hwA-2">
<div class="input">
<label for="hwA-2-serial">#2 - Box Serial Number</label><br />
<input type="text" name="hwA-2-serial" id="hwA-2-serial" />
</div>
<div class="checkbox">
<label>
<input type="checkbox" name="hwA-2-override" value=""> Override Validation
</label>
</div>
</fieldset>
</div> [...]
I've hacked together something that works flawlessly but it's really ugly code and I want to learn to clean it up.
Does anyone have a better suggestion then this method? I've used some attribute selectors to cut down the repetition, but I still have to a huge block for each hardware (there are 4 right now). I guess I can use a loop with variables for the hardware?
$('input[name="hwA-qty"]').click(function(){
var selected = $(this).val();
if (selected == 1) { //Hide inputs 2-5
$('fieldset[id^="hwA"]').hide();
}
if (selected == 2) { //Show inputs 1 & 2
$('fieldset#hwA-2').show();
$('fieldset#hwA-3').hide();
$('fieldset#hwA-4').hide();
$('fieldset#hwA-5').hide();
}
if (selected == 3) { //Show inputs 1-3
$('fieldset#hwA-2').show();
$('fieldset#hwA-3').show();
$('fieldset#hwA-4').hide();
$('fieldset#hwA-5').hide();
}
if (selected == 4) { //Show inputs 1-4
$('fieldset#hwA-2').show();
$('fieldset#hwA-3').show();
$('fieldset#hwA-4').show();
$('fieldset#hwA-5').hide();
}
if (selected == 5) { //Show all inputs
$('fieldset[id^="hwA"]').show();
}
});
$('input[name="hwB-qty"]').click(function(){
var selected = $(this).val();
if (selected == 1) {
$('fieldset[id^="hwB"]').hide();
}
if (selected == 2) {
$('fieldset#hwB-2').show();
$('fieldset#hwB-3').hide();
$('fieldset#hwB-4').hide();
$('fieldset#hwB-5').hide();
}
if (selected == 3) {
$('fieldset#hdPvr2').show();
$('fieldset#hdPvr3').show();
$('fieldset#hdPvr4').hide();
$('fieldset#hdPvr5').hide();
}
if (selected == 4) {
$('fieldset#hdPvr2').show();
$('fieldset#hdPvr3').show();
$('fieldset#hdPvr4').show();
$('fieldset#hdPvr5').hide();
}
if (selected == 5) {
$('fieldset[id^="sdPvr"]').show();
}
}); [...]
And here's the html:
[...]
<div class="hardwareValidation">
<div class="select">
<label for="hwA-qty">Quantity</label><br />
<label>1 <input type="radio" name="hwA-qty" value="1" checked /></label>
<label>2 <input type="radio" name="hwA-qty" value="2" /></label>
<label>3 <input type="radio" name="hwA-qty" value="3" /></label>
<label>4 <input type="radio" name="hwA-qty" value="4" /></label>
<label>5 <input type="radio" name="hwA-qty" value="5" /></label>
</div>
<fieldset id="hwA-1">
<div class="input">
<label for="hwA-1-serial">#1 - Box Serial Number</label><br />
<input type="text" name="hwA-1-serial" id="hwA-1-serial" />
</div>
<div class="checkbox">
<label>
<input type="checkbox" name="hwA-1-override" value=""> Override Validation
</label>
</div>
</fieldset>
<fieldset id="hwA-2">
<div class="input">
<label for="hwA-2-serial">#2 - Box Serial Number</label><br />
<input type="text" name="hwA-2-serial" id="hwA-2-serial" />
</div>
<div class="checkbox">
<label>
<input type="checkbox" name="hwA-2-override" value=""> Override Validation
</label>
</div>
</fieldset>
</div> [...]

您可以使用

遍历方法,该方法选择匹配元素的以下同级元素。请参阅:http://jsfiddle.net/GlauberRocha/s4PAG/1/
You could use the
nextAll
traversing method, that selects the following siblings of the matched elements.See: http://jsfiddle.net/GlauberRocha/s4PAG/1/
