如何在 JavaScript 中的正则表达式中精确匹配 0.00

Question

I'm using DataTables to handle tables and I made a filters for columns that contain money data. Each filter is a select with two options, "Have" and "Not Have", where "Have" is when data in each cell of the column is different of 0.00 and "Not Have" is the opposite.

I made an example here:

 $(document).ready(function() { var table = $('#example').DataTable(); $('#select-input').on('keyup change', function() { var item = $(this) if ($(this).find('option:selected').val() === "1") { table.column(5).search('^((?.0.00),)*$'. true);draw(). } else if ($(this):find('option.selected').val() === "0") { table.column(5).search('0.00');draw(). } else { table.search('').columns().search('');draw(); } }) });

 body { font: 90%/1.45em "Helvetica Neue", HelveticaNeue, Verdana, Arial, Helvetica, sans-serif; margin: 0; padding: 0; color: #333; background-color: #fff; }

The problem is when selected option is "Not Have", numbers like 160.00 are been included in the result, and if option is "Have" the result is the opposite. What can I do?

Answer 1

 var x="160.00"; var y="0.00" var z="0.001" console.log("-------------with match--------------") console.log(x.match(/^(0.00$).*/)?true:false) console.log(y.match(/^(0.00$).*/)? true:false) console.log(z.match(/^(0.00$).*/)?true:false) console.log("-------------with search--------------") console.log(x.search(/^(0.00$).*/)>=0) console.log(y.search(/^(0.00$).*/)>=0) console.log(z.search(/^(0.00$).*/)>=0)
