向Web URL插入参数：第三方应用URL端点生成与JSP代码适配

Got it, let's fix this for you. The issue here is that your target URL has query parameters both before and after the hash (#), which the default form submission won't handle correctly—hash fragments are processed client-side, so the browser would append your search parameter after the hash instead of where you need it.

Here's the modified JSP code that constructs the exact URL you want, with explanations of the key changes:

<form id="summon_form" method="GET" action="//webpage" target="_blank" _lpchecked="1" onsubmit="handleFormSubmit(event);">
    <input type="text" onchange="${gooEvent}" id="srchRes" title="SearchResult" onfocus="if (this.value === 'Enter search term') this.value = '';" placeholder="Enter search term">
    <!-- Add a submit button if you don't already have one in your form -->
    <button type="submit">Search</button>
</form>

<script>
function handleFormSubmit(event) {
    // Stop the browser's default form submission behavior
    event.preventDefault();
    
    // Grab the search term from your input field
    const searchTerm = document.getElementById('srchRes').value.trim();
    
    // Optional: Validate the user entered something
    if (!searchTerm) {
        alert('Please enter a search term first!');
        return;
    }
    
    // Encode the search term to handle special characters (spaces, &, ?, etc.)
    const encodedTerm = encodeURIComponent(searchTerm);
    
    // Build the full target URL with both sets of parameters
    const finalUrl = `https://webpage/search?s.q=${encodedTerm}#!/search?ho=t&fvf=IsFullText,true,f&l=en&q=${encodedTerm}`;
    
    // Open the URL in a new tab (matches your original target="_blank")
    window.open(finalUrl, '_blank');
    
    // Keep your existing double-submit prevention logic
    doubleSubmit.allowSubmitAgainForForm(document.getElementById('summon_form'));
}
</script>

Key Adjustments Made: #

• Custom Submit Handler: Replaced the default form submission with handleFormSubmit to take full control of URL construction.
• URL Encoding: Used encodeURIComponent() to safely encode the search term—this prevents broken URLs when users enter special characters like spaces or ampersands.
• Exact URL Construction: Manually builds the URL with your required parameters, inserting the encoded search term into both the pre-hash (s.q) and post-hash (q) positions.
• Preserved Original Behavior: Keeps the target="_blank" functionality and your existing doubleSubmit logic intact.

Quick Notes: #

• I filled in the truncated onfocus handler with a common pattern (clearing placeholder text)—replace that with your actual existing logic if needed.
• Ensure the doubleSubmit function is loaded before this script runs, or adjust the script order in your page.
