Question

我们最近将jQuery从2.2.4升级到3.1.1，现在看到一些有趣的错误。我安装了jquery-migrate插件，帮助我解决了一些错误，但并非全部。以下是我在Chrome浏览器控制台中看到的错误，我似乎无法确定发生此错误的位置。

jquery-ui-1.12.1.js:1951 Uncaught TypeError: Cannot read property 'step' of undefined
    at String.<anonymous> (jquery-ui-1.12.1.js:1951)
    at each (jquery-3.1.1.slim.js:368)
    at Function.color.hook (jquery-ui-1.12.1.js:1913)
    at jquery-ui-1.12.1.js:1963
    at jquery-ui-1.12.1.js:2005
    at jquery-ui-1.12.1.js:14
    at jquery-ui-1.12.1.js:16

我已经在Chrome中进行了调试，它在一个名为jQuery.fx.step[ hook ]的函数内部中断。当我将鼠标悬停在jQuery.fx上时，它显示为未定义。见下文

jQuery.fx.step[ hook ] = function( fx ) {
            if ( !fx.colorInit ) {
                fx.start = color( fx.elem, hook );
                fx.end = color( fx.end );
                fx.colorInit = true;
            }

我已经卸载jquery-ui，但所有这一切都是打破Angular。如果有人可以对这个问题有所了解，那会很高兴。

packages.config =

Answer 1

根据错误消息，您似乎正在使用jQuery Slim（来自at each (jquery-3.1.1.slim.js:368)）。 Slim显然删除了jQuery UI中所需的一些功能。要解决此问题，请使用完整版的jQuery。

这是一个复制你的问题的演示：

＆＃13;

$( function() {
    // run the currently selected effect
    function runEffect() {
      // get effect type from
      var selectedEffect = $( "#effectTypes" ).val();
 
      // Most effect types need no options passed by default
      var options = {};
      // some effects have required parameters
      if ( selectedEffect === "scale" ) {
        options = { percent: 50 };
      } else if ( selectedEffect === "transfer" ) {
        options = { to: "#button", className: "ui-effects-transfer" };
      } else if ( selectedEffect === "size" ) {
        options = { to: { width: 200, height: 60 } };
      }
 
      // Run the effect
      $( "#effect" ).effect( selectedEffect, options, 500, callback );
    };
 
    // Callback function to bring a hidden box back
    function callback() {
      setTimeout(function() {
        $( "#effect" ).removeAttr( "style" ).hide().fadeIn();
      }, 1000 );
    };
 
    // Set effect from select menu value
    $( "#button" ).on( "click", function() {
      runEffect();
      return false;
    });
  } );

＆＃13;

.toggler { width: 500px; height: 200px; position: relative; }
    #button { padding: .5em 1em; text-decoration: none; }
    #effect { width: 240px; height: 170px; padding: 0.4em; position: relative; }
    #effect h3 { margin: 0; padding: 0.4em; text-align: center; }
    .ui-effects-transfer { border: 2px dotted gray; }

＆＃13;

这里有完整的jQuery：

＆＃13;

$( function() {
    // run the currently selected effect
    function runEffect() {
      // get effect type from
      var selectedEffect = $( "#effectTypes" ).val();
 
      // Most effect types need no options passed by default
      var options = {};
      // some effects have required parameters
      if ( selectedEffect === "scale" ) {
        options = { percent: 50 };
      } else if ( selectedEffect === "transfer" ) {
        options = { to: "#button", className: "ui-effects-transfer" };
      } else if ( selectedEffect === "size" ) {
        options = { to: { width: 200, height: 60 } };
      }
 
      // Run the effect
      $( "#effect" ).effect( selectedEffect, options, 500, callback );
    };
 
    // Callback function to bring a hidden box back
    function callback() {
      setTimeout(function() {
        $( "#effect" ).removeAttr( "style" ).hide().fadeIn();
      }, 1000 );
    };
 
    // Set effect from select menu value
    $( "#button" ).on( "click", function() {
      runEffect();
      return false;
    });
  } );

＆＃13;

.toggler { width: 500px; height: 200px; position: relative; }
    #button { padding: .5em 1em; text-decoration: none; }
    #effect { width: 240px; height: 170px; padding: 0.4em; position: relative; }
