是否可以在另一个之后动态附加 jquery 函数..
这是我尝试过的
$('div#bottomPart').children().getNext(3).children().children().find('p').eq(3).text();
function getNext(num) {
var appendNext = "";
for (var i = 0; i < num; i++) {
appendNext = appendNext + next();
}
return appendNext;
}
不要评判代码,它只是为了让大家了解我的想法。
我正在尝试在选择器中使用 for 循环添加 next()
,例如
如果 getNext(1) 那么它应该返回像 $('div#bottomPart').children().next().children().children().find('p') 这样的选择器。 eq(3).text();
或者如果 getNext(2) 那么它应该返回像 $('div#bottomPart').children().next().next().children().children().find( 'p').eq(3).text();
这是我的 HTML:

因为我正在使用 for 循环(不是上面的循环)根据用户提供的数据在我的 html 中找到 p
标签。
如果有一个附加 next()
函数的解决方案,那对我来说会容易得多..
那有可能吗??
最佳答案
看看这是否对你有帮助:
function getNext(selectorJquery, methodsValues) {
var next = $(selectorJquery);
$(methodsValues).each(function() {
for (var method in this) {
if (this[method] !== null) {
next = next[method](this[method]);
} else {
next = next[method]();
}
}
});
return next;
}
var methodsValues = [
{children: null},
{next: null},
{children: null},
{children: null},
{find: 'p'},
{eq: 3},
{text: null}
];
console.log($('div#bottomPart').children().next().children().children().find('p').eq(3).text());
console.log(getNext($('div#bottomPart'), methodsValues));
var otherMethodsValues = [
{children: null},
{next: null},
{next: null},
{children: null},
{children: null},
{find: 'p'},
{eq: 3},
{text: null}
];
console.log($('div#bottomPart').children().next().next().children().children().find('p').eq(3).text());
console.log(getNext('div#bottomPart', otherMethodsValues));
