Get row count from div

Question

How to get the number of rows from a div? I have to get 2 from the bill. I tried this on jsfiddle but I was not able to get the invoice. All I'm trying to do is get the total and put the score in the rowCountdiv

        <div id="__gvctl00_ctl33_g_1fce23cc_cb78_4993_8f8a_c3369f472afa_ReportGrid__div">
        <table class="ms-WPBody" cellspacing="0" id="ctl00_ctl33_g_1fce23cc_cb78_4993_8f8a_c3369f472afa_ReportGrid" style="border-style:None;width:100%;border-collapse:collapse;width:100%;">
            <tbody><tr class="ms-viewheadertr ms-vhltr">

Answer 1

You can get the number of elements trin the table as follows:

$(".ms-WPBody tr").not(":has(th)").length

This will find all items trwithout a child th.

Full code:

var rowCount = $(".ms-WPBody tr").not(":has(th)").length;
$(".rowCount").text("Num of rows: " + rowCount);

It shows:

Number of lines: 2

And you do not need to use any magic numbers, such as "-1", which can introduce a gross error if the table changes structure.

Answer 2

, jquery. jquery ui.

alert('Num of rows: ' + $('table tr').length );

Hide result

$('#rowCount').html('row');
alert('Num of rows: ' + rows );
