jquery - How to Select a div that has attribute equals to -


i have trouble selecting div's html content selecting div based on attribute value.

my html this:

<div id="infowrap1" class="widgetinfobox" possition="1" wid="qi" style="">.....</div> <div id="infowrap2" class="widgetinfobox" possition="2" wid="cp" style="">.....</div> <div id="infowrap3" class="widgetinfobox" possition="3" wid="pp" style="">.....</div> <div id="infowrap4" class="widgetinfobox" possition="4" wid="mt" style="">.....</div>

lets want html() of div possition=1 ... tried using 

var p1=$(".widgetinfobox [possition='1']").html(); alert(p1);

..but 'undefined', if alert $(".widgetinfobox [possition='1']") [object object]. if select .text() empty string.

how can this? in advance

jquery's sizzle selector engine follows css rules. such, select element using multiple clauses should not add spaces between them. try this:

var p1 = $(".widgetinfobox[possition='1']").html();

it should noted possition , wid not standard attributes of div element. using mean html invalid. should instead use data-* attributes:

<div id="infowrap1" class="widgetinfobox" data-position="1" data-wid="qi" style="">.....</div> <div id="infowrap2" class="widgetinfobox" data-position="2" data-wid="cp" style="">.....</div> <div id="infowrap3" class="widgetinfobox" data-position="3" data-wid="pp" style="">.....</div> <div id="infowrap4" class="widgetinfobox" data-position="4" data-wid="mt" style="">.....</div> 
var p1 = $(".widgetinfobox[data-position='1']").html();
