<p>in my current source code textbox value is 1. when I try <code>alert(isNaN(obj.text())</code> it returns <code>false</code> that is expected but after parseInt when I write <code>alert(a);</code> it returns <code>NaN</code></p> <pre><code>minus.click(function () { var a = 1; if (!isNaN(obj.text())) a = parseInt(obj.text()); if (a > 1) a -= 1; obj.text(a); }); </code></pre> <p>what is the problem?</p> <p>Edit: this is the full code:</p> <pre><code><input type="text" class="basket-txt" value="1" /> jQuery.fn.basket = function (options) { var defaults = { } options = jQuery.extend(defaults, options); this.each(function () { var $this = $(this); $this.height(32).css({ 'line-height': '32px', 'font-weight': 'bold', 'width':'40px', 'text-align':'center', }); var tbl = $('<table border="0" style="border-spacing:0px;float:left;">').appendTo($this.parent()); var tr1 = $('<tr>').appendTo(tbl); var plus = $('<div class="basket-plus">'); $('<td>').append(plus).appendTo(tr1); $('<td>').append($this).appendTo(tr1); var minus = $('<div class="basket-minus">'); $('<td>').append(minus).appendTo(tr1); var tr2 = $('<tr>').appendTo(tbl); $('<td>').appendTo(tr2); $('<td>').appendTo(tr2).append($('<div>').addClass('add-to-basket')); $('<td>').appendTo(tr2); $this.keypress(function (e) { if (e.which < 48 || e.which > 57) e.preventDefault(); }); minus.click(function () { var a = 1; if (!isNaN($this.text())) a = parseInt($this.text()); if (a > 1) a -= 1; $this.text(a); }); plus.click(function () { var a = 1; if (!isNaN($this.text())) a = parseInt($this.text()); if (a < 1000000) a += 1; $this.text(a); }); }); } </code></pre> <p><strong>actually I knew I could correct the code and it would work my concern was to understand why isNaN returns false but parseInt returns NaN</strong></p>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
