So I'm having a problem accessing my json when its in a nested array. I previously had json set up like this with just one array and my .$each function worked perfectly. However I'm having trouble modifying it for this. Json:
{
"tcontent": [{
"Name": "Septicaemia",
"url":"<a>",
"image":"<div class='grid' style='background-image:url(img/anatomy/septicaemia.jpg);'>",
"Variations": [{
"condition":"Community-acquired",
"organisms":"Staph. aureus",
"antimicrobial":"Flucloxacillin ",
"alternative":"(non anaphylaxis): ",
"comments": "Perform full septic screen."
}, {
"Condition":"Community-acquired if intra- abdominal source suspected",
"Organisms":"Predominantly Gram negatives and anaerobes Enterococci may also feature",
"Antimicrobial":"Co-amoxiclav 1.2g iv tds",
"Comments":"Perform full septic screen"
}, {
"Condition":"Healthcare-associated",
"Organisms":"Varies",
"Antimicrobial":"Piperacillin",
"Alternative":"Seek advice from Consultant Microbiologist",
"Comments":"Always"
}]
}, {
"Name": "Infective Endocarditis (IE) (pending blood culture results)",
"url":"<a>",
"image":"<div class='grid' style='background-image:url(img/anatomy/endocarditis.jpg);'>"
}, {
"Name": "Central Nervous System Infections",
"url":"<a>",
"image":"<div class='grid' style='background-image:url(img/anatomy/cns.jpg);'>"
}, {
"Name": "Skin and Soft Tissue Infections",
"url": "<a>",
"image":"<div class='grid' style='background-image:url(img/anatomy/skin.jpg);'>"
}, {
"Name": "Diabetic patients with foot infections",
"url": "<a>",
"image":"<div class='grid' style='background-image:url(img/anatomy/foot.jpg);'>"
}, {
"Name": "Bone and Joint Infections",
"url": "<a>",
"image":"<<div class='grid' style='background-image:url(img/anatomy/bone.jpg);'>"
}, {
"Name": "Intravascular Line Infections",
"url": "<a>",
"image":"<div class='grid' style='background-image:url(img/anatomy/intravascular.jpg);'>"
}, {
"Name": "Urinary Tract Infections",
"url": "<a>",
"image":"<div class='grid' style='background-image:url(img/anatomy/urinary.jpg);'>"
}, {
"Name": "Respiratory Tract Infections",
"url": "<a>",
"image":"<div class='grid' style='background-image:url(img/anatomy/respiratory.jpg);'>"
}, {
"Name": "Gastrointestinal Infections",
"url": "<a>",
"image":"<div class='grid' style='backgroundimage:url(img/anatomy/gastrointestinal.jpg);'>"
}]
}
Here's my javascript to access it.
$(function (){
var imp = "Json/therapy.json"
$.getJSON(imp, function(data) {
var info = "<br>";
$.each(data.tcontent, function(i, item) {
if(item.Name=='Septicaemia'){
var search = item.Variations;
$.each(item.Variations, function(j, subitem) {
info += subitem.condition + subitem.organisms + subitem.antimicrobial + subitem.alternative + subitem.comments
});
$(info).appendTo(".menu");
//alert(item)
};
});
});
});
I've tried a many variations on the var search but nothing seems to be working. I researched a lot of similar problems to this and I've been stuck on this for too long. Any light that can be shed on the situation would be much appreciated!
2 reasons why it doesn't work.
First of all javascript is case sensitive, Your variations differ.
subitem.condition
fails on :
"Condition":"Community-acquired if intra- abdominal source suspected",
"Organisms":"Predominantly Gram negatives and anaerobes Enterococci may also feature",
"Antimicrobial":"Co-amoxiclav 1.2g iv tds",
"Comments":"Perform full septic screen"
So change "Condition" to "condition", etc.etc.
second reason is the
Change $(info).appendTo(".menu");
to $(".menu").append(info)
;
Why?
$(".menu").append(info)
Will just paste the string in the selected DOM element.
But you use
$(info)...
and jquery does all kinds of fancy stuff now.
It tries to either use it as DOM selector, or create a new element.
Because your info starts with <br>
$(info) tries to create a DOM element and it removes all text. Leaving just <br>
because br cannot contain content.
Try to remove the initial <br>
then you will see following error:
Uncaught Error: Syntax error, unrecognized expression:Community-acquiredStaph. aureusFlucloxacillin...
For example if you would type $("hahaha")
, Jquery will try to find the tag <hahaha>
, So when you remove the <br>
your $(info)
is looking for the tag <Community-acquiredStaph. aureusFlucloxacillin...>
<Community-acquiredStaph. aureusFlucloxacillin...>
.
But because your string would then contain weird characters like "-()." It will fail. Hence the above error.
So you can only add html like this:
$("<span>hahah</span>").appendTo($(".menu"));
Or use selector
$("#myDiv").appendTo($(".menu"));
An example when $(info).appendTo(".menu");
working is:
$.each(data.tcontent, function(i, item) {
if(item.Name=='Septicaemia'){
var search = item.Variations;
$.each(item.Variations, function(j, subitem) {
var info = "<p>" + subitem.condition + subitem.organisms + subitem.antimicrobial + subitem.alternative + subitem.comments + "</p>";
$(info).appendTo(".menu");
});
}
});
