unpacked file path
-\pages wxss style files for each page
-app-config.json Summary of page configuration (app.json + configuration file for each page)
-app-service.js Summary of source code js, just format it directly
-page-frame.html summary of wxml files
Mainly deal with the page-frame.html file, you need to modify some of the code inside, the modified code is as follows:
Add wxml output method:
function forwxml(raw){
var str="";
for(var i in raw){
if(i=="tag"){
if(raw[i]!="virtual"){
str+="<"+raw[i];
}
if(raw["wx:for-items"]!=undefined){
str+=" wx:for-items=\""+raw["wx:for-items"]+"\"";
}
if(raw["wx:key"]!=undefined){
str+=" wx:key=\""+raw["wx:key"]+"\"";
}
if(raw["attr"]!=undefined){
for(var j in raw["attr"]){
str+=" "+j+"=\""+raw["attr"][j]+"\"";
}
}
if(raw[i]!="virtual"){
str+=">";
}
if(raw["children"]!=undefined){
for(var k in raw["children"]){
if(typeof(raw["children"][k])=="object"){
str+=forwxml(raw["children"][k]);
}else{
str+=raw["children"][k];
}
}
}
if(raw[i]!="virtual"){
str+="</"+raw[i]+">";
}
}
}
return str;
}Modify the method as follows:
function _v(k) {
if (typeof(k) != 'undefined') return {
tag: 'block',
'wx:for-items': k,
children: []
};
return {
tag: 'virtual',
children: []
};
}
function _n(tag) {
$gwxc++;
if ($gwxc >= 16000) {
throw 'Dom limit exceeded, please check if there\'s any mistake you\'ve made.'
};
return {
tag: 'wx-' + tag,
attr: {},
children: [],
n: [],
raw: {},
generics: {}
}

function makeup(file, suffix) {
var _n = typeof(file) === "number";
if ( _n && Ca.hasOwnProperty(file)) return "";
if ( _n ) Ca[file] = 1;
var ex = _n ? _C[file] : file;
var res="";
for (var i = ex.length - 1; i >= 0; i--) {
var content = ex[i];
if (typeof(content) === "object")
{
var op = content[0];
if ( op == 0 )
res = transformRPX(content[1]) + "px" + res;
else if ( op == 1)
res = suffix + res;
else if ( op == 2 )
res = makeup(content[1], suffix) + res;
}
else
res = content + res
}
console.log(res);
return res;
