求Adobe可填写印章JavaScript脚本：实现印章放置时用户输入数字功能（已有自动填充日期脚本）

Since you already have a solid auto-fill date script for your Adobe fillable stamp, here's a clean JavaScript snippet that adds the functionality to prompt users for a number when they place the stamp. This will play nicely with your existing date logic:

// This script runs when the stamp is placed
function stampNumberInput() {
    // Prompt user for a number - customize the message as needed
    var userInput = app.response({
        cQuestion: "Please enter your reference number:",
        cTitle: "Number Input",
        cDefault: "",
        cLabel: "Reference Number:"
    });

    // Validate the input is a number (adjust validation rules if needed)
    if (userInput !== null && !isNaN(parseFloat(userInput)) && isFinite(userInput)) {
        // Replace "NumberField" with the actual name of the field in your stamp where you want the number to appear
        this.getField("NumberField").value = userInput;
    } else if (userInput !== null) {
        // Alert if invalid input, then re-prompt
        app.alert("Please enter a valid number.", 1, 0);
        stampNumberInput();
    }
    // If user clicks Cancel (userInput is null), the field will remain empty or retain default value
}

// Call the function when the stamp is placed
stampNumberInput();

Key Notes for Integration: #

• Field Name Match: Make sure NumberField matches the exact name of the text field in your stamp where you want the user's number to display. Double-check this in your stamp's field properties!
• Validation Adjustments: The current validation checks for a finite number—if you need to restrict to integers, positive numbers, or a specific range, tweak the condition (e.g., userInput >= 1 && userInput <= 100 for a 1-100 range).
• Combine with Date Script: If your existing date script runs on stamp placement too, just merge the two functions or call both in sequence. For example:

  // Your existing date function
  function autoFillDate() {
      var today = new Date();
      var dateString = util.printd("mm/dd/yyyy", today);
      this.getField("DateField").value = dateString;
  }
  
  // Combined execution
  autoFillDate();
  stampNumberInput();
  

• User Experience: The prompt will pop up immediately when the stamp is placed. If the user clicks Cancel, the number field stays empty—you can set a default value in the cDefault parameter if you want a fallback.

This should fit right into your existing stamp setup without breaking the date auto-fill you already have working.
