[英]How to add threshhold onclick() jQuery?
如何在滑塊中的圖像上添加點擊閾值? 問題是,如果我通過單擊並拖動圖片將滑塊移至其他頁面,則會選擇該圖片。
我如何添加閾值或其他閾值,以便當我從一張幻燈片移動到另一張幻燈片時不會被選中?
第二個問題可能是:如何在不移動的情況下選擇圖像(因為如果我選擇一個圖像,另兩個圖像都在移動),並且我希望它們以滑動器為中心(它們與底部,頂部,左側和右側之間的距離相同)
我希望我使用jQuery和jQuery mobile的phonegap移動應用程序具有這種效果。 我也使用swiper插件。
這是代碼: http : //jsfiddle.net/alecstheone/pDNJ7/

兩個問題。 首先,您在使用2.5px邊框時遇到了舍入錯誤。 嘗試將其更改為2或3px。 其次,邊框有效地在圖像周圍添加了2-3px的空白,這導致它們跳轉。 嘗試在添加邊框時消失的圖像周圍留有空白。 像這樣:
.image {
width:180px;
height:180px;
margin: 3px;
}
.selected {
border-style: solid;
border-color: black;
border-width: 3px;
margin: 0;
}
至於點擊圖片時不刷卡。 按照noSwiping: true
API,在初始化您的Swiper時添加noSwiping: true
,並將類swiper-no-swiping
到您不想swiper-no-swiping
的任何元素上。 我已將其添加到以下jsfiddle第一頁的3個<img>
標記中:
要在滑動時不突出顯示/不突出顯示,請嘗試以下代碼:
mySwiper.addCallback('SlideChangeStart', function(swiper){
sliding = true;
}) ;
mySwiper.addCallback('SlideChangeEnd', function(swiper){
sliding = false;
}) ;
$(".image").click(function() {
if(!sliding){
if($(this).hasClass("selected"))
$(this).removeClass("selected");
else
$(this).addClass("selected");
}
});
您可以檢查是否自從按下鼠標按鈕直到松開鼠標為止,是否將鼠標移動了一定距離,因為松開鼠標按鈕后會觸發click事件。 當行進距離過高時,則禁止選擇。 您可以將鼠標的起始位置存儲在一個變量中,並在單擊事件中對其進行檢查。
$(".image").click(function() {
if(distancetravelled>treshhold)
{
if($(this).hasClass("selected"))
$(this).removeClass("selected");
else
$(this).addClass("selected");
}
});
$(".image").onmousedown(function()
{
startposition = currentMousePos
});
