求助：我的脚本无法在Microsoft Edge(IE)中运行该如何解决？

Hey there! Let’s break down why your jQuery 1.9.1 script runs fine in Chrome but fails in IE, and go through actionable fixes beyond just adding return false;:

First, Check IE’s Developer Tools (Critical!) #

IE’s biggest clue to what’s broken is its error console. Press F12 to open the Developer Tools, then switch to the Console tab. Look for red error messages—they’ll tell you exactly what’s failing (e.g., undefined variables, syntax errors, missing methods).

Common jQuery 1.9.x + IE Issues & Fixes #

• Deprecated jQuery Methods
  jQuery 1.9 removed several outdated methods like .live(), .die(), and the old click-based .toggle(). If your script uses these, replace them with modern alternatives:

  • Replace .live() with .on() (use event delegation syntax: $(document).on('click', '.element', function() { ... }))
  • Replace the old click .toggle() with a custom function to handle state changes.

• IE Document Mode Compatibility
  IE often defaults to a "compatibility mode" that mimics older versions, breaking modern scripts. Force IE to use its latest available mode by adding this meta tag in your <head>:

  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  

  Place this tag before any other scripts or stylesheets to ensure it takes effect.

• ES6+ Syntax Isn’t Supported
  IE (even IE11) doesn’t support ES6 features like arrow functions (() => {}), let/const, template strings, or destructuring. If your script uses these, convert them to ES5:
  ❌ Bad (IE will break):

  $('.my-btn').click(() => {
    let value = $('#input').val();
    console.log(`Value: ${value}`);
  });
  

  ✅ Good (IE-compatible):

  $('.my-btn').click(function() {
    var value = $('#input').val();
    if (typeof console !== 'undefined') { // Avoid IE console errors when dev tools are closed
      console.log('Value: ' + value);
    }
  });
  

• Script Loading Order & Paths
  IE is stricter about script loading order and paths than Chrome. Double-check:

  • jQuery loads before your custom script (your current code looks okay here, but confirm the scripts/variablegenerat... path is correct—IE might fail silently if the script file can’t be found).
  • Avoid async/defer attributes on scripts unless you’re sure they won’t cause dependency issues.

• return false; Misuse
  return false; only works in jQuery event handlers to stop default behavior and prevent event bubbling. If you added it to a non-event function (like an initialization script), it won’t fix anything. Make sure you’re using it in the right context—for example:

  $('a.prevent-link').click(function() {
    // Your code here
    return false; // Stops the link from navigating
  });
  

Next Steps #

1. Open IE’s Console (F12) and note any error messages—this will narrow down the problem instantly.
2. Test each fix above based on the errors you see.
3. If you’re still stuck, share the full code of your variablegenerat... script and the exact error messages from IE’s console—this will help pinpoint the issue faster.
