jQuery：对于input元素的每个属性，我如何获得该输入元素的名称？(jQuery: For each attribute of an input element how do I get that input element's name?)

我正在查看每个具有名为“isDate”属性的输入元素。 我想找到属性父输入元素的name属性。

<input name="A0000" isDate="true" value="01/01/2020" /> <input name="A0001" isDate="true" value="01/01/2021" /> <input name="A0002" isDate="true" value="01/01/2022" /> <input name="A0003" isDate="true" value="01/01/2023" /> <input name="A0004" isDate="true" value="01/01/2024" /> <input name="A0005" isDate="true" value="01/01/2025" /> $("input[isDate="true"]).each(function(){ var _this = this; // do stuff then... // get name of input var name = $(_this).parent().attr("name").val(); // this doesn't work });

I'm looking at each input element that has an attribute named "isDate". I want to find that attributes parent input element's name attribute.

<input name="A0000" isDate="true" value="01/01/2020" /> <input name="A0001" isDate="true" value="01/01/2021" /> <input name="A0002" isDate="true" value="01/01/2022" /> <input name="A0003" isDate="true" value="01/01/2023" /> <input name="A0004" isDate="true" value="01/01/2024" /> <input name="A0005" isDate="true" value="01/01/2025" /> $("input[isDate="true"]).each(function(){ var _this = this; // do stuff then... // get name of input var name = $(_this).parent().attr("name").val(); // this doesn't work });

最满意答案

this将引用元素，而不是属性，因此您不需要.parent()

$("input[isDate='true']").each(function(){ // get name of input var name = $(this).attr("name"); });

我也修改了一些你的语法！

this will reference the element, not the attribute, so you won't need .parent()

$("input[isDate='true']").each(function(){ // get name of input var name = $(this).attr("name"); });

I also fixed some of your syntax too!
