我试图通过单击按钮将XML代码还原或生成一个块,并将其设置为我的工作场所。但是它不能正常工作,以某种方式它什么也没显示。我们将不胜感激。 我尝试了以下链接:

3。https://developers.google.com/blockly/guides/create-custom-blocks/blockly-developer-tools

我要还原的代码:

value = data[5];      
alert(value );
Blockly.Xml.appendDomToWorkspace(value ,demoWorkspace);

我还尝试了以下方式:

var xml = Blockly.Xml.textToDom(data[5]);
Blockly.Xml.domToWorkspace(xml, demoWorkspace);

块恢复功能:

function restore() {

        $.ajax({
            type: "GET",
            url: "/save_composition",
            content_type : "application/json",
            success: function(data) {
                value = data[5];
                {#console.log(value.replace(/['"]+/g, ''));#}
                var result = value.slice(1, -1);
                alert(result);
                var xml = Blockly.Xml.textToDom(data[5]);
                Blockly.Xml.domToWorkspace(xml, demoWorkspace);
            },
            error: function(xhr, textStatus) {
                   alert(textStatus);
            }});
    }

XML的单个响应是:

<xml xmlns="http://www.w3.org/1999/xhtml">

<block type="controls_repeat_ext" id="J]k6G0~I).TfgP_;:j=S" x="223" y="65">
