好的,我设法以“肮脏”的方式解决了这个问题。该代码可以使用改进,但它为我完成了这项工作,我现在懒得改变它。基本上,我遍历选择的对象,检查它是否在某个时候到达具有指定类的元素。
var inArticle = false;
// The class you want to check:
var parentClass = "g-body";
function checkParent(e){
if(e.parentElement && e.parentElement != $('body')){
if ($(e).hasClass(parentClass)) {
inArticle = true;
return true;
}else{
checkParent(e.parentElement);
}
}else{
return false;
}
}
$(document).on('mouseup', function(){
// Check if there is a selection
if(window.getSelection().type != "None"){
// Check if the selection is collapsed
if (!window.getSelection().getRangeAt(0).collapsed) {
inArticle = false;
// Check if selection has parent
if (window.getSelection().getRangeAt(0).commonAncestorContainer.parentElement) {
// Pass the parent for checking
checkParent(window.getSelection().getRangeAt(0).commonAncestorContainer.parentElement);
};
if (inArticle === true) {
// If in element do something
alert("You have selected something in the target element");
}
};
}
});
