我有红色,蓝色,绿色和金色的三角形,方形,圆形。我需要为颜色和形状做过滤器。例如,如果我选择了红色和圆圈,我将只看到一个红色圆圈 这段代码HTML:
<table border="0">
<tr>
<td width="20%" >
<div id="triangleRed" class="color Red triangle"></div>
<div id="triangleBlue" class="color Blue triangle"></div>
<div id="triangleGreen" class="color Green triangle"></div>
<div id="triangleGold" class="color Gold triangle"></div>
</td>
<td width="20%" align="center">
<div id="squareRed" class="color Red square"></div>
<div id="squareBlue" class="color Blue square"></div>
<div id="squareGreen" class="color Green square"></div>
<div id="squareGold" class="color Gold square"></div>
</td>
<td width="40%" align="center">
<div id="circleRed" class="color Red circle"></div>
<div id="circleBlue" class="color Blue circle"></div>
<div id="circleGreen" class="color Green circle"></div>
<div id="circleGold" class="color Gold circle"></div>
</td>
<td width="40%" >
Filter:
<br/>
<div class="searchColor" id="filterColor">
<div class="searchTextColor"> Color: </div>
<input type="checkbox" id="Red" value="Red" />Red
<br/>
<input type="checkbox" id="Blue" value="Blue"/>Blue
<br/>
<input type="checkbox" id="Green" value="Green"/>Green
<br/>
<input type="checkbox" id="Gold" value="Gold"/>Gold
<p/>
</div>
<div class="searchColor" id="searchShape">
<div class="searchShape"> Shape:</div>
<div class="paintSelect">
<input type="checkbox" id="triangle" value="triangle" />triangle
<br/>
<input type="checkbox" id="circle" value="circle"/>circle
<br/>
<input type="checkbox" id="square" value="square"/>square
</div>
</div>
</td>
</tr>
我已经为过滤器编写了这段代码:
$(document).ready(function() {
$("div[class='searchColor'] input").change(function () {
var k = this.value;
switch ($('input:checked').length) {
case 0:
$('.color').show();
return;
case 1:
if (this.checked) {
$('.color').hide();
}
}
if($("div [class='paintSelect'] input").checked){
if (this.checked) {
$('.' + this.value).show();
} else {
$('.' + this.value).hide();
}
}
$('.' + this.value).toggle();
});
});
但代码工作不正确。如果你在形状之后选择颜色,或者相反。你可以看到不正确的答案。 我的错误在哪里?
答案 0 :(得分:1)
您需要考虑4个场景
1:颜色&amp;形状未选中
2:选择了颜色但没有形状
3:选择的形状但不是颜色
4:都选中了
然后你可以显示全部并隐藏未选中或隐藏全部并使用第一种方式显示所有选中的
if($("#filterColor input:checked").length == 0 && $("#searchShape input:checked").length == 0){
$('.color').show();
}else if($("#filterColor input:checked").length == 0 && $("#searchShape input:checked").length > 0){
$('.color').show();
$("#searchShape input:not(:checked)").each(function() {
$('.' + $(this).attr('value')).hide();
});
}else if($("#filterColor input:checked").length > 0 && $("#searchShape input:checked").length == 0){
$('.color').show();
$("#filterColor input:not(:checked)").each(function() {
//console.log(this,$(this).attr('value'),$('.'+$(this).attr('value')))
$('.' + $(this).attr('value')).hide();
});
}else{
$('.color').show();
$("#searchShape input:not(:checked)").each(function() {
$('.' + $(this).attr('value')).hide();
});
$("#filterColor input:not(:checked)").each(function() {
//console.log(this,$(this).attr('value'),$('.'+$(this).attr('value')))
$('.' + $(this).attr('value')).hide();
});
}
