한 번의 마우스 클릭으로 모든 DIV 텍스트 선택

한 번의 마우스 클릭으로 모든 DIV 텍스트 선택

---

사용자가 DIV를 클릭 할 때 DIV 태그의 내용을 강조 표시 / 선택하는 방법 ... 모든 텍스트가 강조 표시 / 선택되므로 사용자가 마우스로 텍스트를 수동으로 강조 표시 할 필요가 없으며 약간의 텍스트를 그리워?

예를 들어 아래와 같이 DIV가 있다고 가정합니다.

<div id="selectable">http://example.com/page.htm</div>

... 사용자가 해당 URL을 클릭하면 전체 URL 텍스트가 강조 표시되어 브라우저에서 선택한 텍스트를 쉽게 드래그하거나 마우스 오른쪽 단추를 클릭하여 전체 URL을 복사 할 수 있습니다.

감사!

function selectText(containerid) {
    if (document.selection) { // IE
        var range = document.body.createTextRange();
        range.moveToElementText(document.getElementById(containerid));
        range.select();
    } else if (window.getSelection) {
        var range = document.createRange();
        range.selectNode(document.getElementById(containerid));
        window.getSelection().removeAllRanges();
        window.getSelection().addRange(range);
    }
}

<div id="selectable" onclick="selectText('selectable')">http://example.com/page.htm</div>

이제 ID를 인수로 전달해야합니다.이 경우 "선택 가능"하지만 더 광범위하므로 chiborg에서 언급 한 것처럼 jQuery를 사용하지 않고 여러 번 어디서나 사용할 수 있습니다.

2017 업데이트 :

노드의 컨텐츠 호출을 선택하려면 다음을 수행하십시오.

window.getSelection().selectAllChildren(
    document.getElementById(id)
);

이것은 IE9 + (표준 모드)를 포함한 모든 최신 브라우저에서 작동합니다.

실행 가능한 예 :

function select(id) {
  window.getSelection()
    .selectAllChildren(
      document.getElementById("target-div") 
    );
}

#outer-div  { padding: 1rem; background-color: #fff0f0; }
#target-div { padding: 1rem; background-color: #f0fff0; }
button      { margin: 1rem; }

<div id="outer-div">
  <div id="target-div">
    Some content for the 
    <br>Target DIV
  </div>
</div>

<button onclick="select(id);">Click to SELECT Contents of #target-div</button>

더 이상 사용되지 않으므로 아래의 원래 답변은 더 window.getSelection().addRange(range); 이상 사용되지 않습니다.

원래 답변 :

위의 모든 예는 다음을 사용합니다.

    var range = document.createRange();
    range.selectNode( ... );

그러나 문제는 DIV 태그 등을 포함하여 노드 자체를 선택한다는 것입니다.

OP 질문에 따라 노드의 텍스트를 선택하려면 대신 전화해야합니다.

    range.selectNodeContents( ... )

따라서 전체 스 니펫은 다음과 같습니다.

    function selectText( containerid ) {

        var node = document.getElementById( containerid );

        if ( document.selection ) {
            var range = document.body.createTextRange();
            range.moveToElementText( node  );
            range.select();
        } else if ( window.getSelection ) {
            var range = document.createRange();
            range.selectNodeContents( node );
            window.getSelection().removeAllRanges();
            window.getSelection().addRange( range );
        }
    }

순수한 CSS4 솔루션이 있습니다.

.selectable{
    -webkit-touch-callout: all; /* iOS Safari */
    -webkit-user-select: all; /* Safari */
    -khtml-user-select: all; /* Konqueror HTML */
    -moz-user-select: all; /* Firefox */
    -ms-user-select: all; /* Internet Explorer/Edge */
    user-select: all; /* Chrome and Opera */

}

user-selectCSS 모듈 수준 4 사양으로, 현재 초안 및 비표준 CSS 속성이지만 브라우저는이 속성을 잘 지원합니다 ( caniuse.com/#feat=user-select 참조) .

MDN 에서 사용자 선택 에 대한 자세한 내용을 읽고 여기에서 w3scools로 재생 하십시오.

The answer of Neuroxik was really helpful. I had only a trouble with Chrome, because when I clicked on an external div, It did not work. I could solve it removing the old ranges before add the new range:

function selectText(containerid) {
    if (document.selection) {
        var range = document.body.createTextRange();
        range.moveToElementText(document.getElementById(containerid));
        range.select();
    } else if (window.getSelection()) {
        var range = document.createRange();
        range.selectNode(document.getElementById(containerid));
        window.getSelection().removeAllRanges();
        window.getSelection().addRange(range);
    }
}
<div id="selectable" onclick="selectText('selectable')">http://example.com/page.htm</div>

For content editable stuff (not regular inputs, you need to use selectNodeContents (rather than just selectNode).

NOTE: All the references to "document.selection" and "createTextRange()" are for IE 8 and lower... You'll not likely need to support that monster if you're attempting to do tricky stuff like this.

function selectElemText(elem) {

    //Create a range (a range is a like the selection but invisible)
    var range = document.createRange();

    // Select the entire contents of the element
    range.selectNodeContents(elem);

    // Don't select, just positioning caret:
    // In front 
    // range.collapse();
    // Behind:
    // range.collapse(false);

    // Get the selection object
    var selection = window.getSelection();

    // Remove any current selections
    selection.removeAllRanges();

    // Make the range you have just created the visible selection
    selection.addRange(range);

}

Using a text area field, you could use this: (Via Google)

<form name="select_all">

    <textarea name="text_area" rows="10" cols="80" 
    onClick="javascript:this.form.text_area.focus();this.form.text_area.select();">

    Text Goes Here 

    </textarea>
</form>

This is how I see most websites do it. They just style it with CSS so it doesn't look like a textarea.

This snippet provides the functionality you require. What you need to do is add an event to that div that which activates fnSelect in it. A quick hack that you totally shouldn't do and possibly might not work, would look like this:

document.getElementById("selectable").onclick(function(){
    fnSelect("selectable");
});

Obviously assuming that the linked to snippet had been included.

I found it useful to wrap this function as a jQuery plugin:

$.fn.selectText = function () {
    return $(this).each(function (index, el) {
        if (document.selection) {
            var range = document.body.createTextRange();
            range.moveToElementText(el);
            range.select();
        } else if (window.getSelection) {
            var range = document.createRange();
            range.selectNode(el);
            window.getSelection().addRange(range);
        }
    });
}

So, it becomes a reusable solution. Then you can do this:

<div onclick="$(this).selectText()">http://example.com/page.htm</div>

And it will selected test in the div.

How about this simple solution? :)

<input style="background-color:white; border:1px white solid;" onclick="this.select();" id="selectable" value="http://example.com/page.htm">

Sure it is not div-construction, like you mentioned, but still it is worked for me.

Niko Lay: How about this simple solution? :)

`<input style="background-color:white; border:1px white solid;" onclick="this.select();" id="selectable" value="http://example.com/page.htm">`

.....

Code before:

<textarea rows="20" class="codearea" style="padding:5px;" readonly="readonly">

Code after:

<textarea rows="20" class="codearea" style="padding:5px;" readonly="readonly" onclick="this.select();" id="selectable">

Just this part onclick="this.select();" id="selectable" in my code worked fine. Selects all in my code box with one mouse click.

Thanks for help Niko Lay!

$.fn.selectText = function () {
    return $(this).each(function (index, el) {
        if (document.selection) {
            var range = document.body.createTextRange();
            range.moveToElementText(el);
            range.select();
        } else if (window.getSelection) {
            var range = document.createRange();
            range.selectNode(el);
            window.getSelection().addRange(range);
        }
    });
}

Above answer is not working in Chrome because addRange remove previous added range. I didnt find any solution for this beside fake selection with css.

Easily achieved with the css property user-select set to all. Like this:

div.anyClass {
  user-select: all;
}
