Retrieve first 2 characters of this.title attribute, and call corresponding id
提问by dylfreak6494
I am trying to retrieve the first two characters of a link's title attribute, store it into a variable, and then call that variable as a function. In the code, where it says "#" + s, is where I want that value to be placed. Any ideas?
我试图检索链接标题属性的前两个字符，将其存储到一个变量中，然后将该变量作为函数调用。在代码中，它说"#" + s，是我想要放置该值的地方。有任何想法吗？
$(".flow").click(function() {
if (labelstatus = 1) {
$('.rmflow a,.weflow a,.scflow a,.coflow a,.wcflow a').css({
color: "#b7b7b7"
});
$("." + this.title + " a").css({
color: "#3e3e3e"
});
$("#" + this.title).parent().animate({
opacity: '1'
});
$('.initiate').animate({
opacity: '.4'
}, 100);
// variable to be put in the below selector
$("#" + s).parent().animate({
opacity: '1'
});
$('.info').fadeOut(200);
$("#" + this.title).fadeIn(1000);
return false;
}
else {
}
});

get the first 2 characters in the title:
var s = $(this).attr("title").substr(0, 2);
获取标题的前 2 个字符：
var s = $(this).attr("title").substr(0, 2);

Get first two of attribute and find target based on it.
获取属性的前两个并根据它找到目标。
$('.flow').click(function() {
var first2 = $(this).attr('customatt').substr(0, 2);
$('#' + first2).doSomething();
return false;
});
