在JavaScript中包含jQuery

Include jQuery in JavaScript

本文关键字:jQuery 包含 JavaScript      更新时间:2023-09-26

我有两段代码想一起工作,但我无法将这个jQuery片段正确地集成到JavaScript中…

JavaScript:

(function(){
// Creates the plugin
tinymce.create('tinymce.plugins.mygallery', {
    // Creates control instances based on the control's ID.
    createControl : function(id, controlManager) {
        if (id == 'mygallery_button') {
            // Creates the button
            var button = controlManager.createButton('mygallery_button', {
                title : 'MyGallery Shortcode', // Title of the button
                image : '../wp-includes/images/smilies/icon_mrgreen.gif', // Path to the button's image
                onclick : function() {
                    // Triggers the thickbox
                    var width = jQuery(window).width(), H = jQuery(window).height(), W = ( 720 < width ) ? 720 : width;
                    W = W - 80;
                    H = H - 184;
                    tb_show( 'My Gallery Shortcode', '#TB_inline?width=' + W + '&height=' + H + '&inlineId=mygallery-form' );
                }
            });
            return button;
        }
        return null;
    }
});
// Registers the plugin
tinymce.PluginManager.add('mygallery', tinymce.plugins.mygallery);

// Executes this when the DOM is ready
jQuery(function(){

// Creates a form to be displayed everytime the button is clicked
    var form = jQuery('<div id="mygallery-form"><table id="mygallery-table" class="form-table">'
        <form id="myForm">'
            <div id="input1" style="margin-bottom:4px;" class="clonedInput">'
                Name: <input type="text" name="name1" id="name1" />'
            </div>'
            <div>'
                <input type="button" id="btnAdd" value="add another name" />'
                <input type="button" id="btnDel" value="remove name" />'
            </div>'
        </form>'
        </div>');
    […]
});
})()

jQuery:

$(document).ready(function() {
        $('#btnAdd').click(function() {
            var num     = $('.clonedInput').length; // how many "duplicatable" input fields we currently have
            var newNum  = new Number(num + 1);      // the numeric ID of the new input field being added
            // create the new element via clone(), and manipulate it's ID using newNum value
            var newElem = $('#input' + num).clone().attr('id', 'input' + newNum);
            // manipulate the name/id values of the input inside the new element
            newElem.children(':first').attr('id', 'name' + newNum).attr('name', 'name' + newNum);
            // insert the new element after the last "duplicatable" input field
            $('#input' + num).after(newElem);
            // enable the "remove" button
            $('#btnDel').attr('disabled','');
            // business rule: you can only add 5 names
            if (newNum == 5)
                $('#btnAdd').attr('disabled','disabled');
        });
        $('#btnDel').click(function() {
            var num = $('.clonedInput').length; // how many "duplicatable" input fields we currently have
            $('#input' + num).remove();     // remove the last element
            // enable the "add" button
            $('#btnAdd').attr('disabled','');
            // if only one element remains, disable the "remove" button
            if (num-1 == 1)
                $('#btnDel').attr('disabled','disabled');
        });
        $('#btnDel').attr('disabled','disabled');
});

仅供参考:JS用表单(WordPress)创建了一个弹出窗口,我想用jQuery片段实现用户可以动态添加更多输入字段的功能。

谢谢你的帮助!

您可以将jQuery片段放在javascript代码之后。这不应该是问题所在,因为jQuery代码只是绑定事件。

但是,我不知道#btAddd和#btndl在哪里。问题可能是,元素是在运行jQuery代码后创建的,因此当您调用以下代码时:$('#btnAdd').click(function(){...});元素#btAddd不在那里。

试试这个:$(document).on('click', '#btnAdd', function(){...});

这将把点击事件绑定到文档(始终存在),而不是#btAddd。不过,为了提高性能,您应该将它绑定到#btAddd的父级,当文档准备好时,您确信该父级存在。
