显示外部弹出框的Google字体

Posted 2021-04-15

我们从JSON获取Text [Text1和Text2]并在页面中显示，一旦用户点击Text，我们就会显示弹出框....

要求：

我想在下拉列表中的弹出框中显示所有谷歌字体....

问题 ：

谷歌字体显示在弹出框之外而不是内部....

逻辑：

无论我在模板标签内写的代码应该显示在弹出框内....但这里显示在外面....

    <template id='template2'>
    <input type="range" min="40" max="80" oninput="fontRange(this)"
    <script>

    $(function() {
        $('#font').fontselect().change(function() {

            // replace + signs with spaces for css
            var font = $(this).val().replace(/+/g, ' ');

            // split font into family and weight
            font = font.split(':');

            // set family on paragraphs 
            $('p').css('font-family', font[0]);
        });
    });

    </script>
    </template>

脚本

$('.container').append(
            '<div id="font"><a id ="' + layer.name + '" onclick="openPopUp(' + lightId + ')"' +
            '<div class="txtContainer" id = "text" contenteditable="true" ' +
            'style="' +
            'left: ' + layer.x + 'px; ' +
            'top: ' + layer.y + 'px; ' +
            'font-size: ' + layer.size + 'px; ' +
            '">' + layer.text + '</div></a></div>  ' +
            '<div id="light' + layer.name + '" class="white_content" style="' +
            'left: ' + layer.x + 'px; ' +
            'top: ' + layer.y + 'px; ' + '"> ' +
            $('#template2').html() + 
            '<a href="javascript:void(0)" onclick="closePopUp(' + lightId + ')">Close</a></div> <div>'
        );

以下是代码段：

//font color
var className;

function changeColor(data) {
    var color = $(data).css('background-color');
    var changeColor = $(className).css('color', color);
}

//font color end


// Display pop up next to text
function closePopUp(el) {
    el.style.display = 'none';
    openID = null
}

function openPopUp(el) {
    ///console.log(" open is called ",id)
    if (openID != null) {
        closePopUp(openID)
    }
	
	//font color

    var colorID = el.id.substring(5);
    className = '#' + colorID;

    //font color end
	
    el.style.display = 'block';
    openID = el;
}

function fontRange(e) {
  var element = e.parentElement.id;
  element = "#edit_" + element.split("_")[1];
  $(element).css('font-size', e.value + 'px');

答案

访问我为你完成的这个codepen https://codepen.io/anon/pen/dLmpeL

我在其中添加了名为className的全局类，并在className中添加了id。

现在我得到popup的样式值并添加到下拉列表并添加一些px看起来不错

var styleTop = el.style.top;
var styleLeft = el.style.left;

styleTop = parseInt(styleTop.substring(3 , -1)) + 130;
styleLeft = parseInt(styleLeft.substring(3 , -1)) + 30;

console.log(styleTop);
console.log(styleLeft);

$('.font-select:first').css({
    display: 'block',
    left: styleLeft + 'px',
    top: styleTop + 'px',
    zIndex: 1010
});

希望你喜欢。
