How to call a function on click of a checkbox which is a popup on click of d3 element like rect

Question

I am having a rectangle which is d3 element, I want to click on that rect and a popup should come which will be having checkbox. On click of that checkbox a function should be called.
As of now when I call a function in the html, that particular function is not invoked

mini.append("g").selectAll("miniItems")
            .data(data)
            .enter().append("rect")
            .attr("id", "rect")
            .attr("x", 200)
            .attr("y", function(d,i) {return y2(i*1.2)+5;})
            .attr("width", windowWidth - 700)
            .attr("height", 15)
            .attr("stroke", "grey")
            .on("click", onClick);/*on click of d3 element this function is invoked*/

  function onClick(d){
     let content;
    content = "<div style='background: white;width:70px; box-shadow:3px 3px 5px #797878;height:30px; padding:8%'><input type='checkbox' id='myCheck' (click)='onClaim(d.executionId)'></input>"+ "claim" + "</div>";
     div.html(content)
       .style("left", (d3.event.pageX) + "px") 
        .style("top", (d3.event.pageY) + "px")
        .style("display", "block");
   }

 function onClaim(value){/*this function is not executed*/
        console.log(value);
}

I am not getting any solution in order to invoke that function
Any help is appreciated. Thank you in advance :)

Answer 1

You have some issues with quotes in your code. Try this:

 content = "<div style='background: white;width:70px; box-shadow:3px 3px 5px #797878;height:30px;'>
       <input type='checkbox' onClick='onClaim(d.data);'>
     </div>"

You were closing the surrounding " at the end of 30px;. I replaced that with a single quote and added a double quote at the very end.

Hlo dkshaaa,

you can try this.

Since you are using checkbox instead of onClick you can use onChange.

So instead of this

<input type='checkbox' id='myCheck' (click)='onClaim(d.executionId)'>

you can use

<input type="checkbox" id="isCheckBox" (change)="onClaim($event, d.executionId)"/>

and in angular component you can use the event as

function onClaim(event, execId) {
    if(event.target.checked){
       //DO SOMETHING
    }
}

hope this helps. ;-)

Why not add events the d3 way as you already are using d3 ?

Within the onClick function, you can bind a click event to the input#myCheck.

div.select('input#myCheck').on('click', function () {
    if(this.checked) // checking if the checkbox is checked
        onClaim(d.executionId);
});

And please post a working snippet which makes it easier to answer (as your post was missing definitions of div , mini etc. Anyway, I created a snippet using sample code here:

 var svg = d3.select('svg#chart'); var div = d3.select('div.tooltip'); var data = [{id: 1, executionId: 1}, {id: 2, executionId: 2}]; svg.append("g").selectAll("miniItems") .data(data) .enter().append("rect") .attr("id", "rect") .attr("x", 100) .attr("y", function(d,i) {return (i*100);}) .attr("width", 100) .attr("height", 15) .style("stroke", "grey") .on("click", onClick);/*on click of d3 element this function is invoked*/ function onClick(d){ let content; content = "<div style='background: white;width:70px; box-shadow:3px 3px 5px #797878;height:30px; padding:8%'><input type='checkbox' id='myCheck'/>"+ "claim" + "</div>"; div.html(content) .style("left", (d3.event.pageX) + "px") .style("top", (d3.event.pageY) + "px") .style("display", "block"); div.select('input#myCheck').on('click', function () { if(this.checked) onClaim(d.executionId); }) } function onClaim(value){/*this function is not executed*/ console.log(value); } 

 div.tooltip { position: absolute; } 

 <script src="https://d3js.org/d3.v4.min.js"></script> <svg id="chart" width="400" height="400"></svg> <div class="tooltip"> </div> 

Hope this helps.
