when I worked on Mini Program project for the first time, I have been stepping on it all the time. Through value= "{{json.content}}" and {{data.json.content}} in the textarea tag, I can"t render it in either way
<textarea class="fs14" value="{{json.content}}" bindinput="_input" rows="3" placeholder="" maxlength="100" hidden="{{dleg3}}">
<text class="currentWordNumber fs12">({{currentNoteLen|0}}/{{noteMaxLen}})</text>
</textarea>
data: {
maxlength: 100,
noteMaxLen: 100,
currentNoteLen: 0,
json: {
id: "",
vcardUserId: "a20",
content: "",
openState: ""
}
},
_input(event) {
let value = event.detail.value,
len = parseInt(value.length)
let that = this
this.setData({
currentNoteLen: len,
"json.content": value
})
},
_getWelcomes() {
model._getWelcomes(this.data.json).then((res) => {
this.data.json = res.data.vcardWelcome
// , this.data.json.contenttextareavalue
console.log("this.data.json", this.data.json);
}).catch((errMsg) => {
console.log(errMsg)
}).finally(() => {
console.log("..")
})
}, data printing
