JavaScript is a weakly typed language, and the system iterates through the JSON data to sort by its own data type, as follows:
| The code is as follows |
Copy Code |
| <script Src= "Jquery.js" ></script>
<script>
var json1 = {
"2": {"name": "1th"},
"1": {"name": "2nd"},
"3": {"name": "3rd"}
}
var json2 = {
"2_str": {"name": "1th www.111cn.net"},
"1_str": {"name": "2nd"},
"3_str": {"name": "3rd"}
}
$.each (Json1, function (i,item) {
alert (i+ ":" +item.name);
});
$.each (json2, function (i,item) {
alert (i+ ":" + Item.name);
});
</script> |
How to sort JSON data by a specified sort:
| The code is as follows |
Copy Code |
| <script src= "Jquery.js" ></script>
<script type= "Text/javascript" >
var json = {"Languages": [
{"id": "1", "name": "PHP", "Sort": "1"},
{"id": "2", "Name": "Jacscript", "Sort": "3"},
{"id": "3", "Name": "PYTHON", "Sort": "4"},
{"id": "4", "Name": "NODE." JS ", sort": "2"}
]};
Sort before www.111cn.net
$.each (json.languages, function (i) {
Alert (json.languages[i].id+ "" +json.languages[i].name+ "Sort:" +json.languages[i].sort);
});
To sort
json["Languages"].sort (function (a,b) {
return a["Sort"] > b["Sort"]? 1: (a["sort"] = = b["Sort"]? 0:-1);
});
After sorting
$.each (json.languages, function (i) {
Alert (json.languages[i].id+ "" +json.languages[i].name+ "Sort:" +json.languages[i].sort);
});
</script> |
