我有一个类似的Html:
<div class="ajouterContainer" id="ajouterContainer1">
<div class="ajouter ajoutersaved" id="ajouter1" data-no="1" style='background-image: url(..."); background-color: rgb(255, 0, 0);' >
<div class="pieceModifierContainer"></div>
<a onclick="return false;" href="#">
<label>INCLUSION</label>
</a>
<span class="pieceFileName">INC-00001_41-H.png</span>
</div>
<span class="submenuOpener opened" id="smo1" style="background-color: rgb(255, 0, 0);">▼<input type="hidden"></span>
</div>
我尝试在ajouterContainer div的click事件中获取ajouter1的data-no属性:
$(".ajouterContainer").on("click", function(event) {
var itemID = $(event.target).attr('id');
var itemNumber = itemID.substring(itemID.length - 1);
var idToFind = "#smo" + itemNumber;
var openerItem = $(event.target).find(idToFind);
if (!openerItem.length) {
$(event.target).css("background-color", "red");
return;
}
//the data-no attribute is 3 by default. I change it using jQuery to 1.
var dataNo = openerItem.siblings().data("no"); //returns 3
$(openerItem).prev().attr("data-no"); // returns 1 (the correct value).
});
openerItem.siblings().data("no");
有什么问题?
在通过代码更改它之前,它可以工作。
答案 0 :(得分:1)
您应该使用$(openerItem).siblings('[data-no]').data('no')
编辑:
问题不在于兄弟姐妹()方法;它是因为您使用了event.target来获取实际点击的子元素,而不是ajouterContainer1
。我已将this
替换为适合您的$(".ajouterContainer").on("click", function(event) {
var itemID = this.id;
var itemNumber = itemID.substring(itemID.length - 1);
var idToFind = "#smo" + itemNumber;
var openerItem = $(this).find(idToFind);
if (!openerItem.length) {
$(event.target).css("background-color", "red");
return;
}
//the data-no attribute is 3 by default. I change it using jQuery to 1.
var dataNo = openerItem.siblings().data("no"); //returns 3
console.log(dataNo);
});
。我希望这会有所帮助:
