禁用双击＆QUOT;变焦＆QUOT;在触摸设备的浏览器选项 [英] Disable double-tap "zoom" option in browser on touch devices

问题描述

我想在指定的元素在浏览器（在触摸设备）停用在双击缩放功能 无禁用所有的缩放功能

I want to disable the double-tap zoom functionality on specified elements in the browser (on touch devices), without disabling all the zoom functionality.

例如：一个元素可事情发生可挖多次。这适用于桌面浏览器（如预期）的罚款，但在触摸设备的浏览器，它会放大。

For example: One element can be tapped multiple times for something to happen. This works fine on desktop browsers (as expected), but on touch device browsers, it will zoom in.

推荐答案

我只是想正确回答我的问题是有些人不看答案下面的评论。所以在这里，它是：

I just wanted to answer my question properly as some people do not read the comments below an answer. So here it is:

(function($) {
  $.fn.nodoubletapzoom = function() {
      $(this).bind('touchstart', function preventZoom(e) {
        var t2 = e.timeStamp
          , t1 = $(this).data('lastTouch') || t2
          , dt = t2 - t1
          , fingers = e.originalEvent.touches.length;
        $(this).data('lastTouch', t2);
        if (!dt || dt > 500 || fingers > 1) return; // not double-tap

        e.preventDefault(); // double tap - prevent the zoom
        // also synthesize click events we just swallowed up
        $(this).trigger('click').trigger('click');
      });
  };
})(jQuery);

我不写这个，我只是修改了它。我发现iOS的唯一版本在这里： https://gist.github.com/2047491 （感谢Kablam）
