Jquery.resizable功能-調整圖示大小顯示不正確

2021-12-19 06:48:05 區塊鏈

編碼和面試挑戰的新手。

他們要求使用 JQuery 制作的儀表板(我以前從未使用過)。來自 W3schools 和堆疊中的大量幫助使我 100% 完成了我需要的功能(即使設計可以改進:功能先潤色后!)

好處之一是具有一些 UI/UX 功能,因此我使 div 可拖動,并且我從Jquery .resizable 功能 - 調整圖示大小顯示不正確

但是當它運行時,調整大小的小圖示似乎與上面頁面上的示例有所不同。

有什么想法可以將它修復回呼整大小圖示,它應該看起來的樣子嗎?

var $linkID, $linkURL

function changeTime(){
    let d= new Date(); //built in JS function
    let mm = ('0'   d.getMinutes()).slice(-2);
    let ss = ('0'   d.getSeconds()).slice(-2);
    document.getElementById("dateTime").innerHTML = `${d.getMonth()}/${d.getDay()}/${d.getYear()} ${d.getHours()}:${mm}:${ss}`;
}

setInterval(changeTime, 1000); //updates the time dynamically.

//Group1
//Click to Show functionality: group 1 
//clicks hide all divs, then uses a "title" attribute as a variable to toggle the associated box showing that title's information. 
//I am no marketer, so the text is some basic info I read on the websites.
$(document).ready(function(){
    $(".clickToShow").click(function(){
        $(".clickToShowBlock").hide();
        let idTag = '#'   this.getAttribute("title");        
      $(idTag).toggle();
    });
  });

//Group 2
//Same as above, except using hover instead of click to show the images.

$(document).ready(function(){    
    $(".hoverToShow").hover(function(){let idTag = '#'   this.getAttribute("title");
        $(idTag).show();
      }, function(){let idTag = '#'   this.getAttribute("title");
        $(idTag).hide();      
      $(".hoverToShowBlock").hide();
    });
  });

  //Group3
  //follows group 1 method, but loads all links at the same time by toggling a button.
  
$(document).ready(function(){
    $("#showLinksButton").click(function(){        
      $(".showLinks").toggle();
    });
  });

  $(function(){
    $("#showLinksButton").click(function () {
       $(this).text(function(i, text){
           return text === "Show Links" ? "Hide Links" : "Show Links";
       })
    });
 })

Jquery .resizable 功能 - 調整圖示大小顯示不正確

uj5u.com熱心網友回復:

您根本沒有使用 jQuery-ui CSS 檔案...

<link rel="stylesheet" href="//code.jquery.com/ui/1.13.0/themes/base/jquery-ui.css">

而且你對div. 的規則太“寬”了因此特定于 rezise 句柄,它需要使用:not()選擇器的例外

div:not(.ui-resizable-handle){

var $linkID, $linkURL

//Click to Show functionality: group 1 
//clicks hide all divs, then uses a "title" attribute as a variable to toggle the associated box showing that title's information. 
//I am no marketer, so the text is some basic info I read on the websites.
$(document).ready(function(){
