基于不同输入筛选data属性，如何实现结果默认隐藏选中后显示

Got it, let's break this down into simple, actionable steps to get the behavior you want:

1. Hide Results on Initial Load #

First, ensure your filter results are hidden when the page first loads. You can use either CSS or jQuery—pick whichever fits your setup better:

Option A: CSS (Cleaner for Initial State) #

Add this to your stylesheet to hide the results container by default:

.results-container {
  display: none;
}

(Replace .results-container with the actual class/id of your results element.)

Option B: jQuery (For Dynamic Initial Hiding) #

If you prefer using JavaScript to handle the initial state, add this to your document ready function:

$(document).ready(function() {
  $('.results-container').hide();
});

2. Update Your Filter Logic to Show Results on Selection #

Now, modify your existing code to show results only when the selection criteria are met (and hide them if criteria aren't satisfied after a selection). Here's how to adjust your original code:

// Assuming this code lives inside a change event handler for your selection elements
$('.filter-control').on('change', function() {
  // Your existing regex definitions (replace with your actual patterns)
  const regExName = /your-name-regex/;
  const regExA = /your-a-regex/;
  const regExB = /your-b-regex/;
  const regExTest = /your-test-regex/;

  // Original validation check
  const rtnData = $(this).attr("data-name").match(regExName) && 
                  $(this).attr("data-a").match(regExA) && 
                  $(this).attr("data-b").match(regExB) && 
                  $(this).attr("data-test").match(regExTest);

  // Toggle visibility based on filter result
  if (rtnData) {
    $('.results-container').show(); // Show results when criteria pass
  } else {
    $('.results-container').hide(); // Hide if criteria fail
  }
});

Bonus: Require All Selections Before Showing Results #

If you want results to only appear when the user has completed all required selections (not just a single change), add a check for fully filled filters:

// Check if all filter controls have a value selected
const allFiltersCompleted = $('.filter-control').filter(function() {
  return $(this).val() === '';
}).length === 0;

// Only show results if all filters are filled AND criteria pass
if (allFiltersCompleted && rtnData) {
  $('.results-container').show();
} else {
  $('.results-container').hide();
}

(Replace .filter-control with the selector for your dropdowns/selection inputs.)

That’s it! Now your results will stay hidden until the user makes their selections, and only appear when the filter criteria are satisfied.
