Performing the task of removing a complete script using D3 or JavaScript

Here is the current setup I have in my code:

The index.html file contains

<div id="div1"></div> 

and I dynamically load a file into it (when a socket arrives) using this script:

<script>
    var socket = io.connect('http://127.0.0.1:8080');
    socket.on('load', function () {
        $("#div1").load("sources/load.html);
    });
</script> 

This feature works wonderfully, allowing me to add content to a page without the need for refreshes, etc. The added files contain D3 code as well.

Now, the dilemma lies in removing that loaded content when necessary. I attempted to achieve this by loading another file (load2.html) which includes code for removal.

Removing content in the following form poses no issues:

<div id="div10"> HI </div> 

Using:

d3.select(#div10).remove(); 

This will successfully remove "HI". However, the challenge arises when trying to remove the "generated script" itself. For instance, if the loaded file (load.html) looks like this:

<div id="rm1">
<script>
d3.select("body").append("p").text("D3 tooooo!!!");
var svgContainer = d3.select("body").append("svg")
                                 .attr("width", 200)
                                 .attr("height", 200);

//Draw the Circle
var circle = svgContainer.append("circle")
                        .attr("cx", 30)
                        .attr("cy", 30)
                        .attr("r", 20);
</script>
</div>

Applying the following code

d3.select("#rm1").selectAll("*").remove();
$("#rm1").html("");
d3.select("#rm1").remove(); 

does not seem to have an effect on the embedded "d3 script".

Do you have any suggestions or solutions for this issue?

Answer №1

To solve the question, I found a way for d3 to generate an id that could be removed later. In the initial file, I modified the d3 code to add a div with a specific id:

var rm = d3.select("body").append("div").attr("id","d1");
rm.append(.......)

Then, when this is loaded in another file:

d3.select("#d1").remove();

This method does the trick effectively.

The issue lied in the inability to remove ids that were not "created" by d3 but existed in the HTML code. I still need to investigate further to understand why...
