问题描述

JQuery UI自动完成插件使用 catcomplete 函数。我是JQuery语法的新手，你能帮我理解如何阅读吗？

The JQuery UI autocomplete plugin uses the catcomplete function. I'm new to the JQuery syntax, can you help me to understand how to read it?

$("#searchTextBox").catcomplete({
    minLength: 1,
    source: $("#searchTextBox").data("url"),
    open: function () {
        $(".ui-autocomplete").css({
            left: $(".ui-autocomplete").position().left - 50 + "px",
            top: $(".ui-autocomplete").position().top - 12 + "px"
        });
    },
    select: function (event, ui) {
        /*code*/
    }
});

什么是catcomplete？

What is catcomplete?

catcomplete 是一个出现在jQuery对象上的属性。它不是核心jQuery的一部分，因此可能在页面上添加了一些其他脚本。

jQuery的自动完成如何调用它？

How does jQuery's autocomplete call it?

我找不到自动填充文档中任何地方提到的 catcomplete ，所以它可能没有。它只修改了页面中元素的CSS，其中的类名表明它们通常受自动完成的影响。

I can't find catcomplete mentioned anywhere in the documentation for autocomplete, so it probably doesn't. It just modifies the CSS of elements in the page with class names that suggest they are normally influenced by autocomplete.

什么是 $（＃ searchTextBox）。示例（{}）？在做什么？我是否定义了一个数组并将其传递给名为Example的函数？

What is $("#searchTextBox").Example({})? doing? Am I defining an array and passing it to a function called Example?

否。您正在创建一个对象。数组将是 [] 。

}
