我有一个屏幕，当用户点击按钮时，使用jQuery＆＃39; .load() 加载新模板，以提供更多选项和过渡。这是在运行中发生的，它意味着向页面添加新的HTML，当脚本恰好被加载时不存在：
(function($) {
$('.go').on("click", function() {
/* Poor man's reactivity. */
var shouldReact = false;
try {
$('.top-part').animate({
opacity: 0,
}, {
step: function() {
$(this).css('transform', 'translate3d(0,-20px,0)');
},
duration: 'slow'
}, 'swing');
$('.go').animate({
opacity: 1,
}, {
step: function() {
$(this).css({
'height': '100%',
'width': '100%',
'margin-top': '0',
'z-index': '0',
'background-color': '#0cff9b'
});
},
duration: 1500
}, 'swing');
$('.go-text').animate({
opacity: 0,
}, {
step: function() {
$(this).css('transition', 'all 1s ease-out');
}
});
shouldReact = true;
} catch (err) {
console.log(err.message);
shouldReact = false;
}
if (shouldReact == true) {
$(this).css({
'cursor': 'initial'
});
$(this).unbind("click");
$(this).one("webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend",
function(event) {
$('.welcome_screen').css({
'background-color': '#0cff9b'
});
$('.bottom-part').remove();
render_screen__first_basic_settings();
});
} else {
console.log("Stop! No need to react.");
}
});
function genesis(screen_name, screen_selector, screen_contents, the_old) {
let handler = '.welcome_screen';
$(handler).prepend(screen_name);
$(screen_selector).load(ABSPATH + screen_contents);
$(the_old).remove();
}
/* Parts */
function render_screen__first_basic_settings() {
/*
Each render of a screen must have a genesis, the template which it builds from and a
cleanse / kill. We remove the old, to make space for the new.
*/
genesis('<div id="screen-1" style="z-index:2;"></div>',
'#screen-1',
'/js/setup_theme_templates/basic_settings.html',
'.top-part');
// This is where I should be able to access the template, but I can't.
}

我加载的模板是：

<h3 class="big-cta">What should we call your blog?</h3>

<form id="myForm" action="#" method="post">

不幸的是，尝试查询$('#basic-settings-template')什么都不返回，我相信这是因为脚本在错误的时间运行，但是它不能解释为什么它会让我自己添加模板，如果DOM已经完成包装。
我怎样才能使这项工作能够使用新添加的HTML？
答案 0 :(得分：0)
jQuery.load接受一个函数作为参数，该函数将在请求完成后运行。
这意味着你可以这样做：
$(screen_selector).load(ABSPATH + screen_contents, function(){
// #basic-settings-template was added to the DOM, you can manipulate it now.
$('#basic-settings-template').....
});
