I'm trying to get simplified relationship between connected mxgraph
Question: I'm trying to get the simplified relationship, once the graph is drawn.
i'm trying to get relationship between connected nodes in json.
Note: solution must work for every drawn state.
Here is codepen:
https://codepen.io/eabangalore/pen/pmELpL
i want to get the relationship from above code snippet.
Expected output (from drawn relationship):
[
{"id":0,"parent":"#","text":"A","child":[{"cid":1,"connectionText":"Bangalore"}]},
{"id":1,"parent":0,"text":"B","child":[{"cid":2,"connectionText":""}]},
{"id":2,"parent":1,"text":"C","child":[{"cid":null,"connectionText":""}]}
];
Please refer codepen, as below snippet is not working.

please help me thanks in advance!!!
Check out this CodePen link which has the modified version of the snippet you gave. In it, you can add new elements and change texts and see an updated json string representing the relationships in the graph: https://codepen.io/tien-q-nguyen2/pen/GaQXBO
I also edited the function a little from the first time I posted this answer.
Note: based on the expected output you put in the original question, there is only one parent per vertex element ({"id":1,"parent":0 <= in the example you gave), so if there are multiple nodes pointing to the same child , the child's parent property will only refer to the first parent's id. I can change the parent's property to be an array that can keep multiple parent's ids if you want.
function getNodesFrom(graph){
var cells = graph.getModel().cells;
var vertices = [], edges = [];
for (var key in cells) {
if (cells[key].isVertex()){
vertices.push(cells[key]);
}
else if (cells[key].isEdge()){
edges.push(cells[key]);
}
}
var simpleVertices = [], simpleEdges = [];
var newIndex = 0;
var newIndexOf = [];
vertices.forEach(function(vertex){
simpleVertices.push({id: newIndex, value: vertex.value});
newIndexOf[vertex.id] = newIndex++;
});
edges.forEach(function(edge){
if (edge.target === null || edge.source === null) return;
simpleEdges.push({
parentId: newIndexOf[edge.source.id],
childId: newIndexOf[edge.target.id],
value: edge.value
});
});
var edgesForParentIndex = [];
var edgesForChildIndex = [];
simpleEdges.forEach(function(edge){
if (edgesForParentIndex[edge.parentId] === undefined){
edgesForParentIndex[edge.parentId] = [];
}
edgesForParentIndex[edge.parentId].push(edge);
if (edgesForChildIndex[edge.childId] === undefined){
edgesForChildIndex[edge.childId] = [];
}
edgesForChildIndex[edge.childId].push(edge);
});
var nodes = [];
simpleVertices.forEach(function(vertex){
var node = {};
node.id = vertex.id;
if (edgesForChildIndex[node.id] === undefined){
node.parent = '#';
} else {
node.parent = edgesForChildIndex[node.id][0].parentId;
}
node.text = (vertex.value === undefined || vertex.value === null) ? '' : vertex.value;
node.child = [];
if (edgesForParentIndex[node.id] === undefined){
node.child.push({cid: null, connectionText: ""});
} else {
edgesForParentIndex[node.id].forEach(function(edge){
var text = (edge.value === undefined || edge.value === null) ? '' : edge.value;
node.child.push({cid: edge.childId, connectionText: text});
});
}
nodes.push(node);
});
return nodes;

I am creating an application with an acrobat dynamic stamp pop up window and I would like it to reflect the stamp comment. My dynamic stamp has some JavaScript that will generate a pop-up window. The information on the pop-up window text field will become part of the stamp. I'm trying to add the contents of the pop-up window in two areas.
On the Dynamic stamp (done)
On the Stamp Comments (need help)
Below I added the JavaScript I currently have. If anyone here can help me find a solution, I'd really appreciate it.
var builder =
{
// These map to Text Fields in the Stamp
textBoxes :
[
{ field:"IsoNum", description:"Isometric Number:", default:function() { return Collab.user; } }
]
}
/*********** belongs to: AcroForm:Calculation:Calculate ***********/
// SEE GLOBAL JAVASCRIPT SECTION FOR CUSTOMIZATION
if (event.source.forReal)
{
var stampDialog = CreateDialog(builder);
app.execDialog(stampDialog);
for (var i = 0; i < builder.textBoxes.length; ++i)
{
var t = builder.textBoxes[i];
this.getField(t.field).value = stampDialog.textBoxResults[i];
}
}
function CreateDialog(dialogBuilder)
{
var sd = new Object();
sd.builder = dialogBuilder;
sd.textBoxResults = new Array();
var optionsElements = new Array();
for (var i = 0; i < dialogBuilder.textBoxes.length; ++i)
{
var view = new Object();
view.type = "view";
view.align_children = "align_row";
view.elements = new Array();
var t = dialogBuilder.textBoxes[i];
var s = new Object();
s.type = "static_text";
s.item_id = "sta" + i;
s.name = t.description;
s.width = 110;
var e = new Object();
e.type = "edit_text";
e.item_id = "edt" + i;
e.width = 150;
view.elements[0] = s;
view.elements[1] = e;
optionsElements[i] = view;
}
var optionsCluster =
{
type: "cluster",
name: "Options",
elements: optionsElements
};
sd.initialize = function(dialog)
{
var init = new Object();
for (var i = 0; i < this.builder.textBoxes.length; ++i)
{
var t = this.builder.textBoxes[i];
var id = "edt" + i;
init[id] = t.default();
}
dialog.load(init);
};
sd.commit = function(dialog)
{
var res = dialog.store();
for (var i = 0; i < this.builder.textBoxes.length; ++i)
{
var t = this.builder.textBoxes[i];
var id = "edt" + i;
this.textBoxResults[i] = res[id];
}
};
sd.description =
{
name: "Stamp Dialog",
elements:
[
{
type: "view",
align_children: "align_fill",
elements:
[
optionsCluster
]
},
{
type: "ok"
}
]
};
return sd;
}
I don't have any specific code but it seems you understand enough Acrobat JavaScript to understand my instructions.
The dialog code runs between the time you select and position the stamp and when the stamp actually gets created. For that reason, you can't set the contents of the note directly in your code because the stamp annotation doesn't actually exist until your commit function finishes. What you have to do instead is create a function that sets the contents of the note inside a timeOut and use a delay of about a half second.
My zingchart's last element's color does not match with legend, and keeps on changing unlike the others. Any Ideas? Everything else works good. Though I'm parsing this data through MySQL database, this is how the JavaScript looks like.
My code:
<script>
var myData = ["12","15","7","20","2","22","10","7","7","10","8","15","9"];
var myData = myData.map(parseFloat);
var myLabels = ["General Verbal Insults","General Beatings\/Pushing","Terrorizing\/Threatening Remarks","False Gossip Inflation (Rumors)","Discrimination","Rough Fighting","Sexual Utterance\/Assaults","General Exclusion","Theft","Racist Utterance\/Assaults","Personal Property Damage","Internet Related (Cyber)","Other\/Unspecified"];
window.onload=function(){
var colorCharacters = "ACDEF0123456789";
var globalStylesArray = [];
var myConfig = {
type: "bar",
legend:{},
title: {
"text":"Showing Results For: Canada",
"color":"green"
},
subtitle: {
"text":"Total Bullying Incidents In Country: 144",
"color":"blue"
},
series : [{"values":[ myData[0] ],"text":"General Verbal Insults",},{"values":[ myData[1] ],"text":"General Beatings/Pushing",},{"values":[ myData[2] ],"text":"Terrorizing/Threatening Remarks",},{"values":[ myData[3] ],"text":"False Gossip Inflation (Rumors)",},{"values":[ myData[4] ],"text":"Discrimination",},{"values":[ myData[5] ],"text":"Rough Fighting",},{"values":[ myData[6] ],"text":"Sexual Utterance/Assaults",},{"values":[ myData[7] ],"text":"General Exclusion",},{"values":[ myData[8] ],"text":"Theft",},{"values":[ myData[9] ],"text":"Racist Utterance/Assaults",},{"values":[ myData[10] ],"text":"Personal Property Damage",},{"values":[ myData[11] ],"text":"Internet Related (Cyber)",},{"values":[ myData[12] ],"text":"Other/Unspecified",}]
};
zingchart.render({
id : 'myChart',
data : myConfig,
width:"100%",
height:500,
});
zingchart.gload = function(p) {
console.log(p);
var graphId = p.id;
var graphData = {};
graphData = zingchart.exec(graphId, 'getdata');
graphData = graphData.graphset[0] ? graphData.graphset[0] : graphData;
console.log(graphData);
createColors(graphData.series[0].values.length);
zingchart.exec(graphId, 'modifyplot', {
data: {
styles: globalStylesArray
}
});
}
function createColors(seriesLength) {
console.log('-------createColor seriesLength: ', seriesLength);
globalStylesArray = [];
for (var i = 0; i < seriesLength; i++) {
var colorString = '#';
for (var j = 0; j < 6; j++) {
colorString += colorCharacters.charAt(Math.floor(Math.random() * (colorCharacters.length - 4)));
}
globalStylesArray.push(colorString);
}
console.log('-----globalStylesArray-------', globalStylesArray);
}
};
</script>
Referring to the comment on the OP:
I just want all color to be different, since i dont know how many elements are in MyData - its generated through PHP & MYSQL
If you just want all of the colors to be different, remove the zingchart.gload function and the createColors function. ZingChart will create different colors for each series dynamically.
If you do want to specify each of those colors ahead of time since you do not know how many series your data will produce, you will need to apply a theme to your chart configuration: http://www.zingchart.com/docs/design-and-styling/javascript-chart-themes/
is there a way to pass data to render
The following code is what I'm currently using:
render:function() {
var background =
var highlight = this.model.get('highlight');
$(this.el).find('div').each(function(index,element) {
if(index < highlight) {
$(element).css({'background': 'url("assets/img/alphabet/ok/ok.png"), url('+background+')'});
$(element).attr('id', 'ok');
} else {
$(element).removeAttr('id');
}
})
}
maybe like this pic:
... you can do something like this:
this.background : [],
//...
initialize : function(){
//...
this.background.push(string.charAt(i));
//...
},
render : function(){
//...
var background = this.background[index];
//...
}
but, maybe also for loop inside your initialize can stay inside render, because it render the view (with .append()).
EDIT NOTE:
I repeat, the possibilities to move around the loop in the initialization function in the render function.
I try to change your backbone view structure:
var WordView = Backbone.View.extend({
initialize : function(){
this.listenTo(this.model,"remove",this.remove);
},
render : function(){
var $Div,
string = this.model.get('string'), //use _string (string can cause some issue in IE)
highlight = this.model.get("highlight"),
letter_width = 36,
letter_heigth = 35,
word_width = string.length * letter_width;
if(this.model.get("x") + word_width > $(window).width()) this.model.set({x:$(window).width() - word_width});
$(this.el).css({
position:"absolute",
top : this.model.get("y"),
left : this.model.get("x")
});
var background,char;
for(var i; i < string.length; i++){
char = string.charAt(i);
background = "url('"+char+"') no-repeat";
$Div.removeAttr("id"); //seems useless
if(i < highlight){
background = "url('assets/img/alphabet/ok/ok.png'),url('"+char+"')";
$Div.id("ok"); //maybe is better $Div.class("ok");
}
$Div = $("<div>").clone();
$Div.css({
width : letter_width,
heigth : letter_height,
float: "left",
"background" : background
}).appendTo($(this.el));
}
}
});
var ButtonFarmAtivada = new Array();
function X() {
var tableCol = dom.cn("td"); //cell 0
//create start checkbox button
ButtonFarmAtivada[index] = createInputButton("checkbox", index);
ButtonFarmAtivada[index].name = "buttonFarmAtivada_"+index;
ButtonFarmAtivada[index].checked = GM_getValue("farmAtivada_"+index, true);
FM_log(3,"checkboxFarm "+(index)+" = "+GM_getValue("farmAtivada_"+index));
ButtonFarmAtivada[index].addEventListener("click", function() {
rp_farmAtivada(index);
}, false);
tableCol.appendChild(ButtonFarmAtivada[i]);
tableRow.appendChild(tableCol); // add the cell
}
1) is it possible to create the button inside an array as I'm trying to do in that example? like an array of buttons?
2) I ask that because I will have to change this button later from another function, and I'm trying to do that like this (not working):
function rp_marcadesmarcaFarm(valor) {
var vListID = getAllVillageId().toString();
FM_log(4,"MarcaDesmarcaFarm + vListID="+vListID);
var attackList = vListID.split(",");
for (i = 0; i <= attackList.length; i++) {
FM_log(3, "Marca/desmarca = "+i+" "+buttonFarmAtivada[i].Checked);
ButtonFarmAtivada[i].Checked = valor;
};
};
For number 1) yes, you can.
function createInputButton(type, index) { // um, why the 'index' param?
// also, why is this function called 'createInputButton'
// if sometimes it returns a checkbox as opposed to a button?
var inputButton = document.createElement("input");
inputButton.type = type; // alternately you could use setAttribute like so:
// inputButton.setAttribute("type", type);
// it would be more XHTML-ish, ♪ if that's what you're into ♫
return inputButton;
}
I don't really understand part 2, sorry.
