Node drag not working on iPad - javascript

I would like to drag node and drag canvas (svg element)
On a desktop browser, it works fine, but on an iPad it only drags the canvas; node dragging is not working. Where did I go wrong?
My source code:
<!DOCTYPE html>
<meta charset="utf-8">
<style>
.node {
stroke: #fff;
stroke-width: 1.5px;
}
.link {
stroke: #999;
}
</style>
<body>
<script src="d3.js"></script>
<script>
var view_w = width = 960,
view_h = height = 500,
view_y = 0,
view_x = 0;
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
.attr("viewBox", view_x+" "+view_y+" "+view_w+" "+view_h);
var canvasdrag = d3.behavior.drag().on("drag", function(d){
view_x -= d3.event.dx;
view_y -= d3.event.dy;
//change svg position
svg.attr("translate", view_x + " " + view_y);
//change viewBox start position
svg.attr("viewBox", view_x+" "+view_y+" "+view_w+" "+view_h);
});
svg.call(canvasdrag);
d3.json("./sample.json", function(error, graph) {
graph.links.forEach(function(d) {
d.source = graph.nodes[d.source];
d.target = graph.nodes[d.target];
});
var link = svg.append("g")
.attr("class", "link")
.selectAll("line")
.data(graph.links)
.enter().append("line")
.attr("x1", function(d) { return d.source.x; })
.attr("y1", function(d) { return d.source.y; })
.attr("x2", function(d) { return d.target.x; })
.attr("y2", function(d) { return d.target.y; });
var node = svg.append("g")
.attr("class", "node")
.selectAll("circle")
.data(graph.nodes)
.enter().append("circle")
.attr("r", 6)
.attr("cx", function(d) { return d.x; })
.attr("cy", function(d) { return d.y; })
.call(d3.behavior.drag()
.origin(function(d) { return d; })
.on("drag", function(d) {
d.x = d3.event.x, d.y = d3.event.y;
d3.select(this).attr("cx", d.x).attr("cy", d.y);
link.filter(function(l) { return l.source === d; }).attr("x1", d.x).attr("y1", d.y);
link.filter(function(l) { return l.target === d; }).attr("x2", d.x).attr("y2", d.y);
}));
});

The code above is using D3js to draw a Force-directed graph drawing from some data, and I just want to place some text on the circle so I use node.append("text") you can see it above.
But however when add it it does not work, there is still not text on the circle so I wonder how could it be????

SVG does not allow a text element inside an circle element. You should put the circle and the text element inside a common g. Try something like this (not tested):
var node = svg.selectAll(".node")
.data(graph.nodes).enter().append('g').classed('node', true);
node.append("circle")
.attr("r", function(d) {return d.r;})
.style("fill", function(d) { return color(d.group); })
.append("title")
.text(function(d) { return d.name; });
node.append("text")
.text("A");
And then instead of setting cx and cy on nodes, set the transform property on the g.node:
force.on("tick", function() {
// ...
node.attr("transform", function(d) { return 'translate(' + [d.x, d.y] + ')'; })
});

D3.js - Text not showing up in node

I found this d3 code, and I am unable to put text to the nodes. I have seen some solutions to create a parent class for this but I am getting errors trying them out. The current code works but doesn't add text :(
Here's the plnkr link for the working code -

You are appending a text to circle as child node. That will not render. A circle can't have a text. There are 2 ways, either define a new enter selection with the same data and append texts ,or create a g element append circle and text and on tick,vupdate transform attribute each tick. I did the first one, change the below part of your script and it will render:
// node.append("title")
// .text(function(d) { return d.name; });
var texts =svg.selectAll(".texts")
.data(graph.nodes)
.enter()
.append("text")
.attr("dx", 12)
.attr("dy", "0.35em")
.text(function(d){ return d.name; });
// .call(force.drag);
// .attr("font-size", function(d){ return d.influence*1.5>9? d.influence*1.5: 9; })
force.on("tick", function() {
link.attr("x1", function(d) { return d.source.x; })
.attr("y1", function(d) { return d.source.y; })
.attr("x2", function(d) { return d.target.x; })
.attr("y2", function(d) { return d.target.y; });
node.attr("cx", function(d) { return d.x; })
.attr("cy", function(d) { return d.y; });
texts.attr("x", function(d) { return d.x; })
.attr("y", function(d) { return d.y; });
});

I have an attribute for each node called clique_nodes which is a list of nodes that need to displayed on mousedown (hide every other node in the graph on mousedown). How do I do this?

You should attach 'mousedown' event handler to your nodes where you filter the "clique_node" attribute and make their opacity 0.
var gnodes = svg.selectAll('g.gnode')
.data(graph.nodes)
.enter()
.append('g')
.classed('gnode', true)
.attr('clique_node', function(d,i){
if(d.attr === "clique_node"){
return true;
}
})
.on("mousedown", function(d,i){
d3.selectAll('.gnode').filter(function(d) {
if(d.attr !== "clique_node"){return d;}
})
.attr("opacity",0);
d3.selectAll('.link').filter(function(d) {
if(d.source.attr !== "clique_node" || d.target.attr !== "clique_node"){return d;}
})
.attr("opacity",0);
});

i need that i will select the nodes using mouse drag as the application is working and the values will come to the console

d3.js move node and label together

In our project I want to add cicrles dynamically when the add node button is clicked and link these circles with an arrow. But When I linked the circles labels of the circles do not move together with circles. The code is below.

How can I solve this problem?

The canonical solution is to put the text and circles into a group. Instead of force.tick() moving both the text and nodes individually, you simply transform the group.
So this:
node.attr("cx", function (d) {
return d.x;
})
.attr("cy", function (d) {
return d.y;
});
text.attr("x", function (d) {
return d.x;
})
.attr("y", function (d) {
return d.y;
});
Becomes this:
node.attr("transform", function(d) { return "translate(" + d.x + "," + d.y + ")"; });
