copied!<p>In JavaScript core used in UltraEdit scripts there is no function to print formatted into a string variable.</p> <p>But it is nevertheless very easy to create aligned strings with leading spaces or zeros.</p> <p>Example for fixed length output of a number:</p> <pre><code>var nNumber = 30; // number to output right aligned with 4 digits var sAlignSpaces = " "; // string containing the spaces (or zeros) for aligning // Convert integer number to decimal string. var sNumber = nNumber.toString(10); // Has the decimal string less than 4 characters as defined by sAlignSpaces? if (sNumber.length < sAlignSpaces.length) { // Build decimal string new with X spaces (here 2) from the alignment // spaces string and concatenate this string with the number string. sNumber = sAlignSpaces.substr(0,sAlignSpaces.length-sNumber.length) + sNumber; } // String sNumber has now always at least 4 characters with // 0 to 3 leading spaces depending on decimal value of the number. </code></pre> <p>Example for aligning positive numbers dynamically depending on highest number:</p> <pre><code>var nHighestNumber = 39428; // highest number usually determined before var nCurrentNumber = 23; // current number to output right aligned // Convert the highest number to a decimal string and get a copy // of this string with every character replaced by character '0'. // With highest number being 39428 the created string is "00000". var sLeadingZeros = nHighestNumber.toString(10).replace(/./g,"0"); // Convert integer number to decimal string. var sNumber = nCurrentNumber.toString(10); // Has the decimal string of the current number less // characters than the decimal string of the highest number? if (sNumber.length < sLeadingZeros.length) { // Build decimal string new with X (here 3) zeros from the alignment // string and concatenate this leading zero string with the number string. sNumber = sLeadingZeros.substr(0,sLeadingZeros.length-sNumber.length) + sNumber; } // String sNumber has now always at least 5 characters with 0 to 4 // leading zeros depending on decimal value of the positive number. </code></pre>
