如何点击Share链接时自动勾选相邻的iCheck复选框？

First, since you have around 50 identical modules, using event delegation is the most efficient approach—it avoids binding 50 separate click events and works even if modules are added dynamically later. Here's how to implement it:

// Use event delegation on a parent container (document works, or a closer static parent if available)
$(document).on('click', '.sharelink', function(e) {
  // Prevent default link action first
  e.preventDefault();
  
  // Find the closest input-group container that holds both the checkbox and share link
  const $moduleContainer = $(this).closest('.input-group');
  
  // Locate the corresponding chk-share checkbox inside this specific module
  const $targetCheckbox = $moduleContainer.find('.chk-share');
  
  // Use iCheck's official API to check the checkbox (critical for syncing the styled UI)
  $targetCheckbox.iCheck('check');
  
  // Proceed with your modal logic here, e.g.:
  // const modalUrl = $(this).data('href');
  // // code to open your modal with modalUrl
});

Key Details & Explanations: #

• Event Delegation: Attaching the click event to a parent element (like document) means we only need one event listener for all .sharelink elements—this is way more performant than binding events to each of the 50 links individually, and it works for links added after the page loads.
• Targeting the Right Checkbox: Using closest('.input-group') ensures we're only looking within the exact module that contains the clicked Share link. Then find('.chk-share') grabs the checkbox specific to that module, so you never accidentally check a checkbox from a different section.
• iCheck API Usage: Don't try to directly set the native checked property of the checkbox! iCheck wraps the native input and manages its own styled UI. Calling iCheck('check') updates both the native checkbox state and the visible styled checkbox to keep them in sync.

Extra Tips: #

• If you want to ensure the checkbox stays checked even on repeated Share clicks, no extra code is needed—iCheck('check') is safe to call multiple times without issues.
• To uncheck the checkbox later (if needed), use $targetCheckbox.iCheck('uncheck') instead.
