[备忘]js点击按钮复制文本

直接上代码:

<script>
	/**
     * 获取标准url参数
     * @param key
     * @returns {*}
     * @private
     */
    function __get(key){
        let search = window.location.search;
        search = search.replace('?', '');
        search = search.split('&');
        let param = {};
        let spl = null;
        for (let i=0; i<search.length; i++){
            spl = search[i].split('=');
            param[spl[0]] = spl[1];
        }
        return param[key];
    }


    /**
     * 复制
     * @private
     */
    function __tocopy() {
        //alert(window.location.search);
        //alert(__get('invitingID'));
        var input = document.createElement("input");
        input.type = 'text';
        input.value = '##@@'+__get('invitingID')+'@@##';
        input.style = 'width:100px;position:absolute;opacity: 0;';
        input.readOnly = true; //在ios上必须加上
        document.body.appendChild(input);
        input.select();
        input.setSelectionRange(0, input.value.length);
        let aaa = document.execCommand('Copy');
        //console.log(aaa)
        document.body.removeChild(input);
    }
</script>

这是我在使用的方法,直接可用。
