雙擊引導圖標可防止事件觸發

[英]Prevent event firing when double click on bootstrap icon

我有一個帶有圖標“加號”的標准卡,單擊該圖標后,該圖標就變成圖標“減號”,並讓用戶看到內容。如果用戶再次單擊此圖標“減號”,則內容將被隱藏,而圖標“加號”將替換圖標“減去”。

看到這里: https : //jsfiddle.net/DTcHh/22354/

它可以正常工作,但問題是至少在我的計算機(chrome 40)和移動設備(android / chrome)上,如果我真的快速單擊了兩次(例如雙擊),所有操作都會“卡住”,而不是看到當沒有內容時,我會看到“加號”圖標。

例如,如果我快速雙擊“加號”圖標,這就是我看到的內容(當“加號”圖標可見時,我不應該看到“這是我的內容”):

在此處輸入圖片說明

該怎么辦?

我嘗試使用反跳腳本和類似以下內容的腳本 ,但是它不起作用:

function debounce(fn, wait) {
  var timeout;
  return function () {
    clearTimeout(timeout);
    timeout = setTimeout(function () {
      fn.apply(this, arguments)
    }, (wait || 1));
  }
}

if (window.addEventListener) {
      // For all major browsers, except IE 8 and earlier
      window.addEventListener('resize', debounce(function () {
        console.log('clicked');        
        clickhere();
      }, 250));

function clickhere() {
  var list = $('.cards-list')
  $('li', list).click(function(e){ 
    var card=$(this);
    $(this).find(".glyphicon").toggleClass("glyphicon-   
  minus").toggleClass("glyphicon-plus");
  });
 }

因為這很棘手,所以不妨與解決方案一起分享更新的jsfiddle

一個簡單的解決方案可能是使用justClicked變量(設置為false onload)來跟蹤我們正在處理雙擊還是單擊:

  1. 點擊到達后,在執行任何操作之前,請查看justClicked===true 如果是這樣,您就知道在最后一秒鍾內發生了一次單擊(請參見下文),您可以e.preventDefault()並退出。
  2. 如果通過了上述檢查,請設置justClicked=true ,調用setTimeout在1000ms內執行,然后繼續使用您的標准點擊處理程序。
  3. 在此期間到達的任何點擊( justClicktrue )都將無法通過步驟1中的檢查,因此被中止。
  4. setTimeout回調中,設置justClick=false 該應用現在可以接收和處理新的點擊了。
<i id="icon" class="glyphicon glyphicon-plus detail-icon_354"></i>

$('#collapseOne_354').on('show.bs.collapse', function() {
  $('#icon').removeClass('glyphicon-plus').addClass('glyphicon-minus');
});
$('#collapseOne_354').on('hide.bs.collapse', function() {
  $('#icon').removeClass('glyphicon-minus').addClass('glyphicon-plus');
});

的jsfiddle

或僅使用CSS:

<i class="glyphicon glyphicon-plus detail-icon_354"></i>

.card-detail-opener[aria-expanded=false] i:before {
  content: '\2b';
}
.card-detail-opener[aria-expanded=true] i:before {
  content: '\2212';
}

對於這種情況,我發現更好的解決方案是使用標志變量,當用戶首次單擊時, clicks將為1,並且將創建setTimeout函數,並在觸發click事件之前等待700ms

如果在700ms延遲之前檢測到另一次點擊(雙擊的情況下),則將清除第一個計時器,並且不會觸發該點擊:

var list = $('.cards-list')
var clicks=0;
var timer=null;

$('li', list).on("click", function(e){
    clicks++;  //count clicks
    var card=$(this);

    if(clicks === 1) {
      //wait a while to check if the second click will be triggered
      timer = setTimeout(function() 
      {
        card.find(".glyphicon").toggleClass("glyphicon-minus")
            .toggleClass("glyphicon-plus");

        clicks = 0; //after action performed, reset counter
      }, 700);
    }
    else 
    {
      clearTimeout(timer);    //prevent single-click action
      clicks = 0;             //after action performed, reset counter
    }
})
.on("dblclick", function(e){
    e.preventDefault();  //cancel system double-click event
});

希望這會有所幫助。

好的,我嘗試了另一種方法。

$('#collapseOne_354').on("hidden.bs.collapse", function(e){
e.preventDefault();
 $(".cards-list").find(".glyphicon").removeClass("glyphicon-
minus").removeClass("glyphicon-plus");
  $(".cards-list").find(".glyphicon").addClass("glyphicon-plus");
});

$('#collapseOne_354').on("shown.bs.collapse", function(e){
 e.preventDefault();
 $(".cards-list").find(".glyphicon").removeClass("glyphicon-
plus").removeClass("glyphicon-minus");
 $(".cards-list").find(".glyphicon").addClass("glyphicon-minus");
});

請讓我知道是否可以進行任何改進。
