This function match sets an attribute (collapsed) to true or false depending on
the value of a string :
function match(children) {
var data = $scope.treeData
for (var i = 0; i < data.length; i++) {
var s = data[i]
for (var i2 = 0; i2 < s.children.length; i2++) {
var s2 = s.children[i2]
for (var i3 = 0; i3 < s2.children.length; i3++) {
for (var i4 = 0; i4 < s2.children[i3].children.length; i4++) {
var text = "";
if ($scope.searchText == undefined) {
text = ""
} else {
text = $scope.searchText
}
if (s2.children[i3].children[i4].label
.toLowerCase() === text.toLowerCase()) {
s2.children[i3].collapsed = false
}
}
}
}
}
}
Excluding the bad use of variable names i3,i2 etc is there a cleaner method ?
As the inner most loop requires access to the outer loop can recursion still be used ?
Update :
Data structure :
[{"label":"test","collapsed":false,"children":[{"label":"test","collapsed":false,"children":[],"$$hashKey":"002"}],"$$hashKey":"001"}]
Update 2 :
Using a recursive function but the string 'test' is not being matched :
http://jsfiddle.net/U3pVM/19196/
fiddle src :
<div ng-app>
<h2>Todo</h2>
<div ng-controller="TodoCtrl">
</div>
</div>
function TodoCtrl($scope) {
var json = [{"label":"test","collapsed":false,"children":[{"label":"test","collapsed":false,"children":[],"$$hashKey":"002"}],"$$hashKey":"001"}]
var searchText = 'test'
function match(node, searchText){
angular.forEach(node.children, function(idx, child){
node.collapsed = child.label.toLowerCase === searchText.toLowerCase
console.log(node.collapsed)
if(child.children.length > 0){
match(child, searchText);
}
});
}
match(json, searchText);
}
Please try this :
function match2(obj) {
if (obj.children) {
for (var i = 0; i < obj.children.length; i++) {
match2(obj.children[i]);
}
}
else {
var text = $scope.searchText ? $scope.searchText : "";
if (obj.label
.toLowerCase() === text.toLowerCase()) {
obj.collapsed = false
}
}
Your JSFiddle is very nearly there. I made a couple of changes for this working JSFiddle.
First, you were passing an array into match and not an object. I changed your json variable to be json instead by removing the outer [], but you could also have fixed this by passing in json[0].
The other change was that you had the two parameters, child and idx, were the wrong way round.
function match(node, searchText){
angular.forEach(node.children, function(child, idx){
node.collapsed = child.label.toLowerCase === searchText.toLowerCase
console.log(node.collapsed)
if(child.children.length > 0){
match(child, searchText);
}
});
}
Here's another way of doing it, using some:
function match (node, searchText) {
node.collapsed = node.children.some(function(child) {
return child.label.toLowerCase === searchText.toLowerCase;
});
angular.forEach(node.children, function(child, idx){
match(child, searchText);
})
}
I think something like this may work for you. I don't know anything about angular there might be something there that would make it easier.
var searchText = ($scope.searchText == undefined) ? "": $scope.searchText;
match($scope.treeData, searchText);
function match(node, searchText){
$.each(node.children, function(idx, child){
node.collapsed = child.label.toLowerCase === searchText.toLowerCase
if(child.children.length > 0){
match(child, searchText);
}
});
}

I'm trying the following code:
var var1 = "";
var var2 = "test";
var var3 = "";
vars = new Array('var1','var2','var3');
var count = 0;
for (var i = 0; i < vars.length; ++i) {
var name = vars[i];
if (field_is_empty(name)) {
count++;
}
}
console.log(count);
function field_is_empty(sValue) {
if (sValue == "" || sValue == null || sValue == "undefined")
{
return true;
}
return false;
}
The result here should have been count = 2 because two of the variables are empty but it's always 0. I guess it must something when using if (field_is_empty(name)) because it might not getting the name converted to the name of the actual var.
PROBLEM 2# Still related
I've updated the code as Karthik Ganesan mentioned and it works perfectly.
Now the code is:
var var1 = "";
var var2 = "test";
var var3 = "";
vars = new Array(var1,var2,var3);
var count = 0;
for (var i = 0; i < vars.length; ++i) {
var name = vars[i];
if (field_is_empty(name)) {
count++;
}
}
console.log(count);
function field_is_empty(sValue) {
if (sValue == "" || sValue == null || sValue == "undefined")
{
return true;
}
return false;
}
And the problem is that if add a new if statement something like this:
if (count == '3') {
console.log('AllAreEmpty');
} else {
for (var i = 0; i < vars.length; ++i) {
var name = vars[i];
if (field_is_empty(name)) {
//Set the empty variables as "1900-01-01"
variableService.setValue(name,"test");
}
}
}
It does nothing and I've tested using variableService.setValue('var1',"test") and it works.
PS: The variableService.setValue is a function controlled by the software I don't know exactly what it does I know if use it like mentioned on above line it works.
In your first attempt you used the variable names as strings when you created an array. You need to either use the values themselves:
vars = new Array(var1,var2,var3);
or if you insist to use them by their names, then you need to find them by names when you use them:
if (field_is_empty(window[name])) {
It does nothing
That's not really possible. It could throw an error, or enter the if or enter the else, but doing nothing is impossible. However, since you intended to use the variables by name in the first place (probably not without a reason) and then you intend to pass a name, but it is a value and it does not work as expected, I assume that your initial array initialization was correct and the if should be fixed like this:
var var1 = "";
var var2 = "test";
var var3 = "";
vars = new Array(var1,var2,var3);
var count = 0;
for (var i = 0; i < vars.length; ++i) {
var v = window[vars[i]]; //You need the value here
if (field_is_empty(v)) {
count++;
}
}
console.log(count);
if (count == '3') {
console.log('AllAreEmpty');
} else {
for (var i = 0; i < vars.length; ++i) {
var v = window[vars[i]];
if (field_is_empty(v)) {
//Set the empty variables as "1900-01-01"
variableService.setValue(vars[i],"test");
}
}
}
function field_is_empty(sValue) {
if (sValue == "" || sValue == null || sValue == "undefined")
{
return true;
}
return false;
}
You definitely incorrectly initialize array, you put strings "var1", "var2", "var3" instead of references to strings (variables).
Try this:
vars = new Array(var1,var2,var3);
Your array is wrong
it should be
vars = new Array(var1,var2,var3);
here is the jsfiddle
When parsing documents using the excellent libxmljs library in Node.js, I stumbled across a case where a lot of nested elements were found, and the only thing I had to do was create a JS object from it.
Here is what the code looks like :
if (node.type() == 'element') {
switch(node.name()) {
case 'element1': {
myObject.element1 = {}
for (var i = 0; i < node.childNodes().length; i++) {
if(node.type() == 'element') {
switch(node.name()) {
case 'element2': {
myObject.element1.element2 = node.text()
...
}}}}}}}}
/* didn't count the number of closing brackets, but you get the idea ^_^ */
Is there a faster or built-in way to do such things, create an object from an XML string (or part of it) using libxmlJS ?
Note that, if it helps, the parsed XML must be validated against a XTD schema (which can really easily be done using this library)
Thanks
Here is some non-working code that can be found on this article :
function XML2jsobj(node) {
var data = {};
// append a value
function Add(name, value) {
if (data[name]) {
if (data[name].constructor != Array) {
data[name] = [data[name]];
}
data[name][data[name].length] = value;
}
else {
data[name] = value;
}
};
// element attributes
var c, cn;
for (c = 0; cn = node.attributes[c]; c++) {
Add(cn.name, cn.value);
}
// child elements
for (c = 0; cn = node.childNodes[c]; c++) {
if (cn.nodeType == 1) {
if (cn.childNodes.length == 1 && cn.firstChild.nodeType == 3) {
// text value
Add(cn.nodeName, cn.firstChild.nodeValue);
}
else {
// sub-object
Add(cn.nodeName, XML2jsobj(cn));
}
}
}
return data;
}
From that code, I could build something that seems to work with the latest libxmljs release, here it is :
function XML2jsobj(node) {
var data = {};
// append a value
function Add(name, value) {
if (data[name]) {
if (data[name].constructor != Array) {
data[name] = [data[name]];
}
data[name][data[name].length] = value;
}
else {
data[name] = value;
}
};
for (var c = 0; c < node.attrs().length; c++) {
var cn = node.attrs()[c];
Add(cn.name, cn.value);
}
// child elements
for (var c = 0; c < node.childNodes().length; c++) {
var cn = node.childNodes()[c];
if (cn.type() == 'element') {
if (cn.childNodes().length == 1 && cn.childNodes()[0].type() == 'text') {
// text value
Add(cn.name(), cn.childNodes()[0].text());
}
else {
// sub-object
Add(cn.name(), XML2jsobj(cn));
}
}
}
return data;
}
I hope this will have helped someone.
I am formatting an array in the function inputCategories, and am unable to correctly add a third argument of "category" - forcing me replicate the function multiple times.
Here is the current state:
Calling the function with arguments.
$scope.categories = inputCategories($scope.item.categories, $scope.settings.categories);
function inputCategories (input, settings) {
var updatedSettings = [];
angular.forEach(input, function(obj) {
updatedSettings.push({"category": obj, "ticked": true});
});
var list = updatedSettings.concat(settings);
list.sort(function(a, b) {
return (a.category > b.category) - (a.category < b.category);
});
for ( var i = 1; i < list.length; i++ ){
if(list[i-1].category == list[i].category) {
list.splice(i,1);
}
}
return list;
};
Here are the places which would require a third argument of "category".
function inputCategories (input, settings) {
var updatedSettings = [];
angular.forEach(input, function(obj) {
updatedSettings.push({****"category"****: obj, "ticked": true});
});
var list = updatedSettings.concat(settings);
list.sort(function(a, b) {
return (a.****category**** > b.****category****) - (a.****category**** < b.****category****);
});
for ( var i = 1; i < list.length; i++ ){
if(list[i-1].****category**** == list[i].****category****) {
list.splice(i,1);
}
}
return list;
};
I think that the issue I am having is because I am mixing up strings and a variable that is a string, inside of the object on the fourth line...?
Perhaps you could do something like this:
function inputCategories (input, settings, category) {
var updatedSettings = [];
angular.forEach(input, function(obj) {
var setting = { "ticked": true };
setting[category] = obj;
updatedSettings.push(setting);
});
var list = updatedSettings.concat(settings);
list.sort(function(a, b) {
return (a[category] > b[category]) - (a[category] < b[category]);
});
for ( var i = 1; i < list.length; i++ ){
if(list[i-1][category] == list[i][category]) {
list.splice(i,1);
}
}
return list;
};
I have some html page with text and need to output all inner HTML from tag b by alphabetical order in lower case. I'm just a begginer, so don't be strict.
My code is here (text is just for example): http://jsfiddle.net/pamjaranka/ebeptLzj/1/
Now I want to: 1) save upper case for inner HTML from tag abbr; 2) delete all similar element from the array (as MABs).
I was trying to find the way to split the array by tag, but all that I've done is:
for(var i=0; i<allbold.length; i++){
labels[i] = allbold[i].innerHTML;
}
var searchTerm = ['abbr'];
var abbr = [];
var keywordIndex;
$.each(labels, function(i) {
$.each(searchTerm, function(j) {
var rSearchTerm = new RegExp('\\b' + searchTerm[j] + '\\b','i');
if (labels[i].match(rSearchTerm)) {
keywordIndex = i;
for(var j=0; j<labels.length; j++){
abbr[i] = labels[i];
}
}
});
});
Vanilla JS solution (no library required, see jsFiddle):
var allbold = document.querySelectorAll("b"),
words = document.querySelector("#words"),
labels = {}, i, word, keys, label;
// first, collect all words in an object (this eliminates duplicates)
for(i = 0; i < allbold.length; i++) {
word = allbold[i].textContent.trim();
if (word === 'Labels:') continue;
labels[word.toLowerCase()] = word;
}
// then sort the object keys and output the words in original case
keys = Object.keys(labels).sort();
for(i = 0; i < keys.length; i++){
label = document.createTextNode("SPAN");
label.textContent = labels[keys[i]];
words.appendChild(label);
// add a comma if necessary
if (i < keys.length - 1) {
words.appendChild(document.createTextNode(", "));
}
}
with one helper:
String.prototype.trim = function () {
return this.replace(/^\s+|\s+$/g, "");
};
jQuery solution (see jsFiddle):
$(".content b").map(function () {
return $("<span>", {text: $.trim(this.textContent)})[0];
}).unique(function () {
return lCaseText(this);
}).sort(function (a, b) {
return lCaseText(a) < lCaseText(b) ? -1 : 1;
}).appendTo("#words");
with two helpers:
$.fn.extend({
unique: function (keyFunc) {
var keys = {};
return this.map(function () {
var key = keyFunc.apply(this);
if (!keys.hasOwnProperty(key)) {
keys[key] = true;
return this;
}
});
}
});
function lCaseText(element) {
return element.textContent.toLowerCase();
}
use the mapping element Is THIS FIDDLE for all upper case else this fiddle after your comment what you need
var maplabels = [];
for(var i=0; i<allbold.length; i++){
if (allbold[i].innerHTML != "Labels:") {
if(maplabels.indexOf(allbold[i].innerHTML) == -1){
maplabels.push(allbold[i].innerHTML);
labels.push('<i>' + allbold[i].innerHTML.toUpperCase() + '</i>');
}
}
}
I need to consume a SOAP web service which, naturally, sends its response in XML, since I'm developing a Appcelerator Titanium mobile app I would prefer the response in JSON. After looking online I converted the response using this Javascript code, it mostly worked but returned results such as the following:
{
"SOAP-ENV:Body" : {
"ns1:linkAppResponse" : {
"ns1:result" : {
#text : true;
};
"ns1:uuid" : {
#text : "a3dd915e-b4e4-43e0-a0e7-3c270e5e7aae";
};
};
};
}
Of course the colons and hashes in the caused problems so I adjusted the code to do a substring on the name and drop off anything before the ':', then a stringified the resulting JSON, removed all the hashes and parsed the JSON again. This is a bit messy for my liking but I end up with something usable.
Here is the xmlToJson code I'm using:
// Changes XML to JSON
function xmlToJson(xml) {
// Create the return object
var obj = {};
if (xml.nodeType == 1) {// element
// do attributes
if (xml.attributes.length > 0) {
obj["#attributes"] = {};
for (var j = 0; j < xml.attributes.length; j++) {
var attribute = xml.attributes.item(j);
obj["#attributes"][attribute.nodeName] = attribute.nodeValue;
}
}
} else if (xml.nodeType == 3) {// text
obj = xml.nodeValue;
}
// do children
if (xml.hasChildNodes()) {
for (var i = 0; i < xml.childNodes.length; i++) {
var item = xml.childNodes.item(i);
var nodeName = item.nodeName.substring(item.nodeName.indexOf(":") + 1);
if ( typeof (obj[nodeName]) == "undefined") {
obj[nodeName] = xmlToJson(item);
} else {
if ( typeof (obj[nodeName].push) == "undefined") {
var old = obj[nodeName];
obj[nodeName] = [];
obj[nodeName].push(old);
}
obj[nodeName].push(xmlToJson(item));
}
}
}
return obj;
};
module.exports = xmlToJson;
Which results in the following JSON:
{
Body : {
linkAppResponse : {
result : {
text : true;
};
uuid : {
text : "9022d249-ea8a-47a3-883c-0f4cfc9d6494";
};
};
};
}
While this returns a JSON object I can use, I would prefer to have the resulting JSON in the following form:
{
result : true;
uuid : "9022d249-ea8a-47a3-883c-0f4cfc9d6494";
};
Mostly so it's less verbose and I can simply call json.result in order check if the query was successful instead of json.Body.linkAppResponse.result.text
Any help is greatly appreciated.
Came up with a working solution, not any less dirty but it works and returns data in the format I want.
function soapResponseToJson(xml) {
var json = xmlToJson(xml).Body;
console.debug(json);
var response = {};
for (var outterKey in json) {
if (json.hasOwnProperty(outterKey)) {
temp = json[outterKey];
for (var innerKey in temp) {
if (temp.hasOwnProperty(innerKey)) {
response[innerKey] = temp[innerKey].text;
}
}
}
}
console.debug(response);
return response;
}
// Changes XML to JSON
function xmlToJson(xml) {
// Create the return object
var obj = {};
if (xml.nodeType == 1) {// element
// do attributes
if (xml.attributes.length > 0) {
obj["#attributes"] = {};
for (var j = 0; j < xml.attributes.length; j++) {
var attribute = xml.attributes.item(j);
obj["#attributes"][attribute.nodeName] = attribute.nodeValue;
}
}
} else if (xml.nodeType == 3) {// text
obj = xml.nodeValue;
}
// do children
if (xml.hasChildNodes()) {
for (var i = 0; i < xml.childNodes.length; i++) {
var item = xml.childNodes.item(i);
var nodeName = item.nodeName.substring(item.nodeName.indexOf(":") + 1).replace('#', '');
if ( typeof (obj[nodeName]) == "undefined") {
obj[nodeName] = xmlToJson(item);
} else {
if ( typeof (obj[nodeName].push) == "undefined") {
var old = obj[nodeName];
obj[nodeName] = [];
obj[nodeName].push(old);
}
obj[nodeName].push(xmlToJson(item));
}
}
}
return obj;
};
module.exports = soapResponseToJson;
console.debug(json):
{
linkAppResponse : {
result : {
text : true;
};
uuid : {
text : "e4f78c5f-1bc2-4b50-a749-19d733b9be3f";
};
};
}
console.debug(response):
{
result : true;
uuid : "e4f78c5f-1bc2-4b50-a749-19d733b9be3f";
}
I'm going to leave this question open for a while in case someone comes up with a better solution.
I feel like this is a fairly ugly solution (hope it doesn't offend you :) ).
Why don't you marshal the xml to an object and then use gson or jackson to map to json.
I don't know what framework you use, in spring for example, you can use jaxb2 to marshal and jackson or gson to transform your object to json.
