(no-inner-html) app/components/sports.ts[717, 9]: It's considered unsafe to use the html() function to write a string to innerHTML: $('.tubing').html(health.title)

if (health.title == "waterS") {
      let that = this;
      let recordPlayersWeight = {};
      this.futureParrot = [];
      this.pastParrot = [];
      this.peacockService.getResponse(health.url, 'get', null)
        .subscribe(recordPlayersWeight => {
            this.gridData = recordPlayersWeight.waterDtos;
            that._recordPlayersWeightSource.recordPlayersWeight(this.gridData);

      title: false,
      visible: false,
      resizable: false,
      actions: [],
      draggable: false,

        $("html, body").css("overflow", "hidden");
        that.isVisible = true;
        $('.tubing').html(health.title);

Answer №1

Using jQuery's .html() function can introduce potential security risks to your webpage if "unsafe" elements such as iframe tags or source tags are accidentally added. If the HTML content is provided by a malicious user, it could lead to a code injection attack (https://en.wikipedia.org/wiki/Code_injection).

In this scenario, where you simply need to insert plain text into the .tubing element, it is recommended to use:

$('.tubing').text( health.title );

This method escapes any HTML special characters like < or >, ensuring they are displayed as text instead of being interpreted as elements. By doing so, you mitigate the risk of code injection and avoid triggering the lint rule.
