我想在jQuery的一个警报中获得点击元素的文本。参见下面的示例https://jsfidle.net/pymd4n04/2/
jQuery(".results").click(function() {
event.preventDefault();
jQuery(this).find('h3').click(function() {
var text = jQuery(this).text();
console.log(text.trim());
alert(text.trim());
});
});
但当我单击第一次时，将显示空警报，而当我单击第二次时，将显示该值，但显示两次警报。并保持递增警报。
如有任何帮助，我们将不胜感激。
提前致谢
由于所有链接都嵌入在h3元素中，您可以在jQuery中更加具体地检索类名为的另一个元素中的所有如下所示：h3元素。results
jQuery(".results h3").click(function() {
其次，在您的代码中，您使用了两个click函数...这是不必要的。上面的代码行..单击类名为.results的元素中的h3元素后，就可以轻松获取该h3元素的文本，如下所示：
jQuery(".results h3").click(function(event) {
event.preventDefault();
var text = jQuery(this).text(); // 'this' refers to the h3 element that you clicked.. not the div with the class .results
alert(text.trim());
});
这是工作的JSFiddle。
不要使用那么多的click事件，只需简单一些:jQuery（“.asp_res_url”）.click（函数（）{}）；
这是可行的：
null
jQuery(".asp_res_url").click(function() {
event.preventDefault();
alert( jQuery(this).text().trim());
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
