问题描述

我试图从localStorage获取值; div元素中的多个点击计数器。
他们存储在点击下key = this.id在localStorage;这些值是div的innerText。



现在:1.我过滤了选择,寻找一个匹配的元素id在arraylocal
2.如果匹配,设置html。

  d3.selectAll(。numberCircle)。filter((d) - > this.id in arraylocal).html(localStorage.getItem((d) - > this.id))




  1. 我想使用'this.id'从localStorage获取值(innerText从元素)。


  2. 如何设置localStorage.getItem(x ???? x)来读取正确的键/值对(其中key = this.id)?


因此:对于每个数组过滤器匹配,我还需要与该匹配相关的localStorage value

解决方案

解决方案:

  updateLabels = function 

var arraylocal,key;

解决方案,因为我为setItem设置了一个字符串值,例如:setItem(string,string)



arraylocal是一个包含这些字符串的数组

  arraylocal = []; 
for(key in localStorage){
arraylocal.push(key);
console.log(arraylocal);
}

每个bubble-label-name都有一个字符串值textValue(d) / p>

当字符串值textValue(d)匹配数组中的字符串'key'时,过滤器更改节点的样式

  d3.selectAll(。bubble-label-name)filter(function(d){
var ref;
return ref = textValue style(border,2px solid red); d)

};


I am trying to get values back from localStorage; multiple click counters in div elements. They were stored on click under key = this.id in localStorage; the values are the innerText of the divs.

Now: 1. I filter the selection looking for a match for element-ids in arraylocal 2. if match, set the html.

   d3.selectAll(".numberCircle").filter((d) -> this.id in arraylocal).html(localStorage.getItem(((d) -> this.id))

  1. I would like to get values ( innerText from elements ) back out of localStorage using 'this.id'.

  2. How can I set localStorage.getItem(x????x) to read the proper key/value pair ( where key = this.id ) ?

Thus: for each array filter match, I also need the localStorage value that is related to that match.

解决方案

Solution:

updateLabels = function() {

var arraylocal, key;

key in localStorage reflects a string in this solution, as I set a string value for setItem, e.g.: setItem(string,string)

arraylocal is an array containing these strings

arraylocal = [];
for (key in localStorage) {
  arraylocal.push(key);
  console.log(arraylocal);
}

each bubble-label-name has a string value textValue(d).

The filter changes the style of the nodes when the string value textValue(d) matches a string 'key' in the array

d3.selectAll(".bubble-label-name").filter(function(d) {
  var ref;
  return ref = textValue(d), indexOf.call(arraylocal, ref) >= 0;
}).style("border", "2px solid red");

};
