How can y开发者_Python百科ou convert an array of strings represented in JSON format and convert this to an HTML bulleted list using jQuery?
var ul = $('<ul>').appendTo('body');
var json = { items: ['item 1', 'item 2', 'item 3'] };
$(json.items).each(function(index, item) {
ul.append(
$(document.createElement('li')).text(item)
);
});
As far as fetching the JSON from your server using AJAX is concerned you could use the $.getJSON()
function.
Live demo.
<script language="JavaScript" type="text/javascript">
// Here is the code I use. You should be able to adapt it to your needs.
function process_test_json() {
var jsonDataArr = { "Errors":[],"Success":true,"Data":{"step0":{"collectionNameStr":"ideas_org_Private","url_root":"http:\/\/192.168.1.128:8500\/ideas_org\/","collectionPathStr":"C:\\ColdFusion8\\wwwroot\\ideas_org\\wwwrootchapter0-2\\verity_collections\\","writeVerityLastFileNameStr":"C:\\ColdFusion8\\wwwroot\\ideas_org\\wwwroot\\chapter0-2\\LastFileName.txt","doneFlag":false,"state_dbrec":{},"errorMsgStr":"","fileroot":"C:\\ColdFusion8\\wwwroot\\ideas_org\\wwwroot"}}};
var htmlStr= "<h3 class='recurse_title'>[jsonDataArr] struct is</h3> " + recurse( jsonDataArr );
alert( htmlStr );
$( document.createElement('div') ).attr( "class", "main_div").html( htmlStr ).appendTo('div#out');
$("div#outAsHtml").text( $("div#out").html() );
}
function recurse( data ) {
var htmlRetStr = "<ul class='recurseObj' >";
for (var key in data) {
if (typeof(data[key])== 'object' && data[key] != null) {
htmlRetStr += "<li class='keyObj' ><strong>" + key + ":</strong><ul class='recurseSubObj' >";
htmlRetStr += recurse( data[key] );
htmlRetStr += '</ul ></li >';
} else {
htmlRetStr += ("<li class='keyStr' ><strong>" + key + ': </strong>"' + data[key] + '"</li >' );
}
};
htmlRetStr += '</ul >';
return( htmlRetStr );
}
</script>
</head><body>
<button onclick="process_test_json()" >Run process_test_json()</button>
<div id="out"></div>
<div id="outAsHtml"></div>
</body>
<!-- QUESTION: Maybe some one with more jquery experience
could convert this to a shorter / pure jquery method -->
A JSON string like that would look like:
'["foo","bar","base","ball"]'
You can parse that into an Javascript array object by calling JSON.parse()
, iterate over that array and insert the strings.
var jsonstring = '["foo","bar","base","ball"]',
arr = JSON.parse(jsonstring),
len = arr.length;
while(len--) {
$('<li>', {
text: arr[len]
}).appendTo('ul');
}
Use jQuery jPut plugin. Just create a html template & call your json file. you can also call the ajax file through jPut (ajax_url)
http://plugins.jquery.com/jput/
<script>
$(document).ready(function(){
var json = [{"name": "item1","link":"link1"},{"name": "item2","link":"link2"}];
//jPut code
$("#menu").jPut({
jsonData:json,
name:"template",
});
});
</script>
<body>
<!-- jput template, the li that you want to append to ul-->
<div jput="template">
<li><a href="http://yourdomain.com/{{link}}">{{name}}</a></li>
</div>
<!-- your main ul -->
<ul id="menu">
</ul>
</body>
If your json strings are in stringArr:
$.each(stringArr, function(idx, val) {
$('<li></li>').html(val);
}
or something among these lines should do it.
Something like this maybe? I haven't tested it, but it should work.
ul = $("<ul/>");
$(json_arr).each(function(){
$("<li/>").text(this).appendTo(ul);
});
// add ul to DOM
