    <p>I have looked through a number of answers on here and none have really helped me. I have noticed a strange issue with my jQuery. I realise that the code is a bit quick and nasty but i will tidy it once i have it working properly. </p> <pre><code>jQuery('input#use_points').change(function() { if(jQuery(this).not(':checked')) { alert('not checked'); jQuery( "#amount" ).val(0); jQuery( "#pounds" ).val(0); jQuery(".ui-slider-handle").css({'left': '0'}); jQuery(".points-text").hide(); jQuery(".use-points-labels").hide(); jQuery("#slider-range-max").hide(); jQuery('#updatecart').click(); } if(jQuery(this).is(':checked')) { alert('is checked'); jQuery( "#amount" ).val(1); jQuery( "#pounds" ).val(0.05); jQuery(".points-text").show(); jQuery(".use-points-labels").show(); jQuery("#slider-range-max").show(); jQuery('#updatecart').click(); } }); </code></pre> <p>You will notice that i have two alerts 'not checked' and 'is checked' The first if statement works as expected. However, if it's not checked and then i click the check box it runs through both statements. Giving me the alert 'not checked' and then followed straight after by 'is checked' </p> <p>However, i don't understand why this is happening since it's only getting called on the change not the click action of the check box. Does anyone have any thoughts ? </p> <p>Thanks in advance.</p> <p>/////////////////////////////// EDIT //////////////////////////////////////////// I have now answered my own question. For some reason writing it this way works:</p> <pre><code>jQuery('input#use_points').change(function() { if(this.checked) { alert('is checked'); jQuery( "#amount" ).val(1); jQuery( "#pounds" ).val(0.05); jQuery(".points-text").show(); jQuery(".use-points-labels").show(); jQuery("#slider-range-max").show(); jQuery('#updatecart').click(); } else { alert('not checked'); jQuery( "#amount" ).val(0); jQuery( "#pounds" ).val(0); jQuery(".ui-slider-handle").css({'left': '0'}); jQuery(".points-text").hide(); jQuery(".use-points-labels").hide(); jQuery("#slider-range-max").hide(); jQuery('#updatecart').click(); } </code></pre> <p>Can anyone explain why ? </p>

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.
