问题 I would like to let the user define the name of a list to be used in the code, so I have been using an input function. I want the user's response to the input function to become the name of the list. I tried the following: a = input("What would you like the name of the list to be? ") a = [] However, this named the list "a" rather than whatever string the user had responded to the input function. How can I let the user name the list? Is there anyway to do this? 回答1: The correct way to

问题 I'm currently trying to create an input number that prevent user to enter a number that is higher than a @Input() maxValue, I implemented it like this : HTML : <input class="number-selector-input" type="number" [(ngModel)]="value" (ngModelChange)="checkValue($event)" /> Typescript : public checkValue(value) { if (value > this.maxValue) { this.value = this.maxValue; } if (value < this.minValue) { this.value = this.minValue; } } It is working quite well but there is still a problem that I can't

问题 I have these increment and decrement buttons that will add or subtract. I will import the default values from props and then want to allow the user to make adjustments.

Is there a way to do this? //HTML <table id="notesplus" cellpadding="0" cellspacing="0"> <thead></thead> <tbody></tbody> </table> //JQUERY $(document).ready(function() { $('input[id=addIt]').live(

问题 With help from Howard E I was able to show the input from a dropdown field into another field as a placeholder. You can find that question here. Now I would like to show the input of any type of input field into a sentence in a paragraph in that same form. I tried this code, but unfortunately that didn’t work. <p>Is [recent-years] is gonna be a good year?</p> [recent-years] is the name of the cf7 input field. In this case a dropdown field. But also would love to know for textfields and radio

问题 I'd like to create an input form that has an asterisk after the box for each required field. If the user enters a string the asterisk should change to a exclamation mark. Right now the javascript code just adds an exclamation mark every time the user types a letter.
